Step-by-step explanation:
How would you limit the domain to
make this function one to one?
f(x) = (x + 3)^2
Answer:
Domain would be x ≥ -3.
So enter -3.
Step-by-step explanation:
This is a parabola with line of symmetry x = -3.
When x has values like say -4 and -2, f(x) will have a value of 1 making the function many to one.
So, to make it one to one, x would have to be equal or greater than -3.
A function assigns values. The limit of the domain to make this function one to one is x≥3.
What is a Function?A function assigns the value of each element of one set to the other specific element of another set.
A one to one function is a function whose every input gives a distinct output. Now given the function is a quadratic function, therefore, the function will have the same output for multiple inputs.
Since the symmetrical axis for this function lies at x=-3, therefore, for the function to be one to one the domain of the function must be greater than or equal to 6.
Hence, the limit of the domain to make this function one to one is x≥3.

[tex] = > 25 \times 386 + 3219 \div 2[/tex]
Answer:
11259.5Step-by-step explanation:
25 × 386 + 3219 ÷ 2 = 9650 + 1609.5 = 11259.5Answer:
11259.5
Step-by-step explanation:
25×386+3219÷2
Multiply 25 and 386 to get 9650.
9650+3219/2
Convert 9650 to fraction 19300/2.
19300/2+3219/2
Since 19300/2 and 3219/2 have the same denominator, add them by adding their numerators.
19300+3219/2
Add 19300 and 3219 to get 22519.
22519/2
Divide 22519 by 2 to get 11259.5.
11259.5

3(4x+6)=x-4
Answer:
x = −2
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
3(4x+6)=x−4
(3)(4x)+(3)(6)=x+−4(Distribute)
12x+18=x+−4
12x+18=x−4
Step 2: Subtract x from both sides.
12x+18−x=x−4−x
11x+18=−4
Step 3: Subtract 18 from both sides.
11x+18−18=−4−18
11x=−22
Step 4: Divide both sides by 11.
[tex]\frac{11x}{11}[/tex] = [tex]\frac{-22}{11}[/tex]
x = −2

Apply distributive property
[tex](a)\ 2a + 7a[/tex]
Apply distributive property [Factor out a]
[tex]2a + 7a = a(2 + 7)[/tex]

Given the function f (x) = x² + 8x + 7, what are the zeros of f?
Answer:
x = - 7, x = - 1
Step-by-step explanation:
To find the zeros let f(x) = 0 , that is
x² + 8x + 7 = 0
Consider the factors of the constant term (+ 7) which sum to give the coefficient of the x- term (+ 8)
The factors are + 7 and + 1 , since
7 × 1 = + 7 and 7 + 1 = + 8 , then
x² + 8x + 7 = 0
(x + 7)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 7 = 0 ⇒ x = - 7
x + 1 = 0 ⇒ x = - 1

For numbers 11-16 Find x, y, and z for each. Show all work.
Answer:
x=74
y=37
z=25
Step-by-step explanation:
First, we can find y.
106 and 2y are supplementary angles. That means that when added together, they equal 180.
106+2y=180
2y=74
y=37
We can use this information to help us find x.
x and 2y are corresponding angles, which means that they are congruent.
2y=x
2(37)=x
74=x
Now, let's find z.
4z+6 is corresponding to the angle right above angle x. This means that (4z+6)+x=180.
Let's solve.
(4z+6)+74=180
4z+80=180
4z=100
z=25

basically you combine like terms on both sides of the division problem separately
which now becomes a^6b^3/a^-5 b^-2
then you divide which is just subtracting the exponents of like terms
a^(6--5) b^(3--2)
and then solve and you get the answer a^11 b^5

Someone help Duane scored 55 points in the last basketball game, which is 10 points more than his previous personal best. LeBron scored 15 points more than Chris in the same game. LeBron scored the same number of points as Dwayne‘s previous personal best. Let D represent the number of points Dwayne scored during his previous personal best and C Represent the number of crest points. Question: how many points did Chris score during the game? If these are the only three players who scored, What was the teams totals number of points at the end of the game?
Answer:
130 points
Step-by-step explanation:
Given
[tex]Scorers: Duane,\ LeBron\ \&\ Chris[/tex]
[tex]D=Dwayne[/tex]
[tex]C = Chris[/tex]
[tex]L = LeBron[/tex]
So, we have:
[tex]L = 15 + C[/tex] --- 15 more than Chris
[tex]L =D -10[/tex] --- Same as Dwayne previous personal best
[tex]D = 55[/tex] -- Dwayne's point
Required
Find the total points
We have:
[tex]L = 15 + C[/tex]
[tex]L =D -10[/tex]
[tex]D = 55[/tex]
Substitute [tex]D = 55[/tex] in [tex]L =D -10[/tex]
[tex]L = 55 - 10[/tex]
[tex]L = 45[/tex]
Substitute [tex]L = 45[/tex] in [tex]L = 15 + C[/tex]
[tex]45 = 15 + C[/tex]
[tex]C =45 -15[/tex]
[tex]C =30[/tex]
So, we have:
[tex]D = 55[/tex]
[tex]L = 45[/tex]
[tex]C =30[/tex]
The total points is calculated as:
[tex]Total = D + L + C[/tex]
[tex]Total = 55 + 45 + 30[/tex]
[tex]Total = 130[/tex]
