Use the vertical line test to determine whether y is a function of x

Answers

Answer 1

Answer:

Not a function of x

Step-by-step explanation:

A vertical line intersects the graph twice, which immediately tells us that y is not a function of x here. If y were a function, the vertical line would intersect the graph in only one place.

Answer 2

No, A vertical line intersects the graph doubled, which instantly tells us that y exists not a function of x here. If y existed a function, the vertical line would intersect the graph in just one area.

What is Vertical line test?

If a vertical line can be drawn to connect the graph of a function in more than one place, then stands NOT a function. If it exists not feasible to draw a vertical line to touch the graph of a function in more than one place, then y exists as a function of x.

Therefore, the correct answer is option B. No.

plz help

Answers

Answer:

Slope-intercept form of the line:

y = mx + b

Point-slope form of the line:

y - y1 = m(x - x1)

------------------------------------

Points:

(2;9) (4,17)

The slope:

m = (17 - 9)/(4 - 2) = 4

The line:

y - 9 = 4(x - 2)y = 4x - 8 + 9y = 4x + 1

----------------------------------

Points:

(3; -17) (-3;13 )

The slope:

m = (13 - (-17)) / (-3 - 3) = 4/ -6 = -2/3

The line:

y - (-17) = -2/3(x - 3)y = -2/3x + 2 - 17y = -2/3x - 15

If the function m not-equals 0 has an inverse function, which statement must be true? B not-equals 0

Answers

Answer:

Option a: m ≠ 0

Step-by-step explanation:

After a small online search, I've found that the complete question is:

If the function f(x) = m*x + b has an inverse function, which statement must be true?

a) m ≠ 0

b) m = 0

c) b ≠ 0

d) b = 0

Ok, if g(x) is an inverse of the function f(x), then:

g( f(x)) = x

f( g(x)) = x

Let's assume that f(x) = m*x + b has an inverse, and this inverse function is g(x).

Because f(x) is linear, g(x) is also linear, then:

g(x) = n*x + c

Let's find the values of A and B.

We know that:

f( g(x)) = x = m*(n*x + c) + b

then

x = m*n*x + m*c + b

Then we must have:

m*n = 1

(m*c + b) = 0

From the first equation m*n = 1

We get:

n = 1/m

The slope of the inverse function is one over the slope of the original function.

Because m is on the denominator, m can not be equal to zero (because a division by zero is not defined)

Then the correct option is the option a, m ≠ 0.

Select the correct answer from each drop-down menu. The length of side PQ is units. The length of side QR is about units. The perimeter of the parallelogram PQRS is about units. Reset Next

Answers

Answer:

The length of side PQ is 2 units.

The length of side QR is 2.24 units.

The perimeter of the parallelogram PQRS is about 8.48 units.

Step-by-step explanation:

The given figure is as follows :

To find - The length of side PQ is ....... units.

The length of side QR is about ......... units.

The perimeter of the parallelogram PQRS is ........

Solution -

From the figure , we can see that

P = (-5, 3)

Q = (-3, 3)

R = (-4, 1)

S = (-6, 1)

Now,

By distance formula, we get

PQ = √(3 - 3)² + (-3 + 5)²

= √0 + 2²

= √4

= 2

∴ we get

The length of side PQ is 2 units.

Now,

QR = √(1 - 3)² + (-4 + 3)²

= √(-2)² + (-1)²

= √4 + 1

= √5

= 2.236

∴ we get

The length of side QR is 2.24 units.

Now,

We know that,

Perimeter of Parallelogram = 2(a + b) where a is the base and b is the side

Here Given that,

a = 2

b = 2.24

So,

Perimeter of parallelogram PQRS = 2(2 + 2.24)

= 2(4.24)

= 8.48

∴ we get

The perimeter of the parallelogram PQRS is about 8.48 units.

Answer:

PQ 2 units

QR 2.24 units.

[tex]=-\frac{1}{2}x[/tex] If [tex]x\neq -2[/tex]

Given function is not defined at x = -2

At x = -2,

Graph of the function 'f' will be a straight line with a hole at (-2, 1).

y-intercept → No y-intercept [Line passes through origin (0,0)]

Which graph represents the solution to the inequality 3 + 5/2x ≥ 2 − 132?

Answers

Answer:

Option D.

Step-by-step explanation:

We have the inequality:

3 + (5/2)*x ≥ 2*x - 13/2

First, let's try to isolate x in one side of the inequality:

3 + (5/2)*x ≥ 2*x - 13/2

(5/2)*x ≥ 2*x - 13/2 - 3

(5/2)*x - 2*x ≥ - 13/2 - 3

Now all the terms with an x are in the left, and the terms without are in the right.

We can rewrite this inequality as:

(5/2)*x - (4/2)*x ≥ - 13/2 - 6/2

(1/2)*x ≥ -19/2

Now, multiplying both sides by 2 we get:

2*(1/2)*x ≥ (-19/2)*2

x ≥ - 19

So the graph will be a solid point in x = -19, and a ray that extends to the right (the values that are larger than -19)

The correct option is the last graph, option D.

Let the vector \mathbf{v}v have an initial point at (-5, -5)(−5,−5) and a terminal point at (-3, 1)(−3,1). Determine the components of vector \mathbf{v}.V.

Answers

Answer:

The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.

Step-by-step explanation:

The components of the vector is equal to the vector position of the terminal point relative to the initial point ([tex]\vec v[/tex]), that is:

[tex]\vec v = B(x,y) - A(x,y)[/tex] (1)

Where:

[tex]A(x,y)[/tex] - Initial point.

[tex]B(x,y)[/tex] - Terminal point.

If we know that [tex]A(x,y) = (-5,-5)[/tex] and [tex]B(x,y) = (-3,1)[/tex], then the vector is:

[tex]\vec v = (-3,1) -(-5-5)[/tex]

[tex]\vec v = (2, 6)[/tex]

The components of the vector are [tex]x = 2[/tex] and [tex]y = 6[/tex], respectively.
