(Select all that are correct) which statements describe key features of function g if g(x) = f(x + 2)
a. y-intercept at (0,4)
b. domain of {x|-♾️< x <♾️}
c. horizontal asymptote of y = 0
d. horizontal asymptote of y=2
e. y-intercept at (0,1)
Answer:
Y-intercept (0,1) / Domain (-infinite,infinite) / horizontal asymptote y=0
The y-intercept is: (0,1)
The domain is [tex]\{x|-\infty < x < \infty\}[/tex]
The horizontal asymptote is [tex]y = 0[/tex]
The given parameters from the complete question are:
[tex]f(x) = 2^{x-2}[/tex]
[tex]g(x) = f(x + 2)[/tex]
First, we calculate the function of g(x)
[tex]g(x) = f(x + 2)[/tex]
Calculate f(x + 2)
[tex]f(x) = 2^{x-2}[/tex]
[tex]f(x + 2) = 2^{x+2-2}[/tex]
[tex]f(x + 2) = 2^x[/tex]
So:
[tex]g(x) = 2^x[/tex]
Start by calculating the y intercept:
This means, we calculate the g(x) when [tex]x=0[/tex]
[tex]g(x) = 2^x[/tex]
[tex]g(0) = 2^0[/tex]
[tex]g(0) =1[/tex]
The above computation means (a) is incorrect; but (e) is correct.
Next, calculate the domain of g(x)
[tex]g(x) = 2^x[/tex]
Some features in a function that limit the x values are: roots, fractions, etc.
[tex]g(x) = 2^x[/tex] does not have any restricting value of x.
This means the value of x ranges from negative infinity to positive infinity.
Hence, the domain is: [tex](-\infty,\infty)[/tex]
The above computation means (b) is correct
Next, calculate the horizontal asymptote.
To do this, we plot the graph of g(x) --> see attachment
Then we trace a horizontal line from the horizontal part of the curve of g(x) till it gets to the y-axis.
From the attached graph of g(x), the line touches the y-axis at [tex]y = 0[/tex]
So, the horizontal asymptote is: [tex]y = 0[/tex]

A pilot takes a taxi from the airport and the hotel. The taxi driver charges a $2.50 fee plus $2.65 per mile. Write an equation that can be used to find y, the total cost of the trip, if x represents the number of miles on the trip.
Answer:
2.50 + 2.65x = y
Step-by-step explanation:
The 2.50 fee won't change but the price per mile will, each mile will cost $2.65 more. And since we don't know how many miles the plot is taking, $2.65x. Then the total cost is y
Answer:
Step-by-step explanation: if the 2.50 is staying the same, then the answer is y=2.50x + 2.65

Una recta que pasa por los puntos A (2,1) y B (6,3) y otra recta pasa por A y por el punto (0,y) ¿Cuánto vale y, si ambas rectas son perpendiculares?
The translation of the question given is
A line that passes through the points A (2,1) and B (6,3) and another line passes through A and through the point (0, y). What is y worth, if both lines are perpendicular?
Answer:
y = 5
Step-by-step explanation:
Line 1 that passes through A (2,1) and B (6,3)
Slope (m1) = 3-1/6-2 = 2/4 = 1/2
y - 1 = [tex]\frac{1}{2}[/tex] ( x -2)
2y - 2 = x- 2
y = [tex]\frac{x}{2}[/tex]
Line 2 passes through A (2,1) and (0,y)
slope (m2) =[tex]\frac{y-1}{-2}[/tex]
Line 1 and Line 2 are perpendicular
m1*m2 = -1
[tex]\frac{1}{2}[/tex] * [tex]\frac{y-1}{-2}[/tex] = -1
y-1 = 4
y = 5
slope = -2
Equation of Line 2
Y-1 = -2(x-2)
y -1 = -2x +4
2x +y = 5
Lea solves the equation below by first squaring both sides of the equation.
3+2y=√-y
What extraneous solution does Lea obtain?
y=
Answer: IF YOU ARE ON KHAN ACADEMY THE ANSWER IS NOT -1
THE CORRECT ANSWER ON KHAN IS -9/4
For equation 3 + 2y = √(-y) the extraneous solution does Lea obtain is y = (-13 + √97) / 8 or y = (-13 - √97) / 8
What is quadratic equation?A quadratic equation is a second-order polynomial equation in a single variable x , ax²+bx+c=0. with a ≠ 0 .
When Lea squares both sides of the equation 3 + 2y = √(-y), she gets:
(3 + 2y)² = (-y)
Expanding the left side, we get:
9 + 12y + 4y² = -y
Bringing all the terms to one side, we get a quadratic equation:
4y² + 13y + 9 = 0
We can solve this quadratic equation using the quadratic formula:
y = (-b ± √(b² - 4ac)) / 2a
Substituting the coefficients a = 4, b = 13, and c = 9, we get:
y = (-13 ± √(13² - 4(4)(9))) / 2(4)
y = (-13 ± √97) / 8
So the solutions are:
y = (-13 + √97) / 8 or y = (-13 - √97) / 8
Hence, the extraneous solution does Lea obtain is y = (-13 + √97) / 8 or y = (-13 - √97) / 8

T is 375 miles from San Francisco to Los Angeles. On a map of California, the scale shows that 2 centimeters equals 10 actual miles. How far apart on the map are the two cities?
Answer:
75 cm
Step-by-step explanation:
the ratio of centimeter to miles is 2:10 or 1:5 (1 cm = 5 mi)
this ratio can be changed to a fraction (1/5)
so now we can set up this equation:
(1/5) = (x/375)
where x = cm on the map
if it makes it easier to understand:
(1cm/5mi) = (xcm/375mi)
now we solve for x:
375(1/5) = x
x = 375/5
x = 75 cm

The area of a rectangular door is 21 ft. Sq. The border around the door is 20 feet. What is the length and width of the door? Use the factors of 21 to help you find the area of the door first.
Answer:
Length = 7 feet, and width is 3 feet.
Step-by-step explanation:
For the given rectangular door,
area = length x width
21 = length x width ................. 1
Also,
perimeter = 2 ( length + width)
20 = 2 ( length + width)
10 = length + width ............ 1
Given that the factors of 21 are required to get the are of the door.
Then, from equation 1;
21 = 7 x 3
And from equation 2;
10 = 7 + 3
So that, the length of the door is 7 feet and its width is 3 feet.

Answer:
1. 6n - 15
2. x + 10
3. -4d + 15
4. true, associative property
5. distributive, commutative
Step-by-step explanation:
1. distribute 3/4 into the parentheses, so multiply 3/4 * 8 and 3/4 * -20
2. distribute the 2 into the parentheses so multiply 2 * 3x and 2 * 5, then combine like terms
3. distribute -3 into the parentheses so -3 * 4D and -3 * -5 then add like terms
4. add like terms on both sides of the equal sign and you get 10x on both sides. this is the associative property because it doesn't matter what's inside or outside the parentheses you get the same answer no matter how you add them up
5. the first part is distributive because you distributed the three into the parentheses and the second part is commutative because you switch them around and you can get the same answer
