First, simplify the (x+2)(x+2) with FOIL:
f(x)=( $x^{2} +2x+2x+4$ )-3
Combine like terms
f(x)= $x^{2} +4x+1$
Then you have standard form.

Hope that helps.

Answer:

A

Step-by-step explanation:

Formula is y=(x-h) Where h is the number the function is moved left or right...since it is supposed to be moved right, then (x-9) should probably work

Solve. 2 (x - 1/2) = 3 (5 - 2x) show the steps in your solution.

viktelen [127]

Question 1.). Solve:

2 (x - 1 / 2) = 3 (5 - 2x)

Simplify both sides of equation:

2( x - 1 / 2 ) = 3(5 - 2x )

(2) (x) + (2) ( -1 / 2 ) = (3) (5) + (3) ( -2x )

Distribute:

2x + - 1 = 15 + -6x

2x - 1 = -6x + 15

Add 6x to both sides:

2x - 1 + 6x = -6x + 15 + 6x

8x - 1 = 15

Add 1 to both sides:

8x - 1 + 1 = 15 + 1

8x = 16

Divide both sides by 8:

8x / 8 = 16 / 8

Answer: 2 (x - 1 / 2) = 3 (5 - 2x) ==========> x = 2

Question 2.).

M =======> Amount Malik need

Solution: =========> m ≥ 5

Inequality ========> 8 + 7 + 10 + m ≥ 30

25 + m ≥ 30

Interpretation ==========> Malik needs at least, $5 .00 to get to, $30.00 or more.

Is the solution reasonable ===========> YES

Hope that helps!!!!! : )

Evaluate the function.<br> f(x) = 3x2 + 16<br> Find f(-1)

SIZIF [17.4K]

Answer:

$f(-1)=19$

Step-by-step explanation:

<u>Evaluating Functions</u>

Given a function y=f(x), evaluate the function for x=a means substituting the variable for the given value.

We have the function:

$f(x)=3x^2+16$

Find f(-1):

$f(-1)=3(-1)^2+16$

$f(-1)=3(1)+16$

$f(-1)=3+16$

$\boxed{f(-1)=19}$
