Question

Hey can someone show me the steps to solving this? Also to whoever keeps taking my stuff down this is a self pace online class i'm taking over the summer to prepare for the SAT's. It's not for a class and im not cheating so stop.

Answer 1

f(-2) = 12

Explanation:

Hello!

To evaluate f(x) to -2, we plug in -2 for x in the equation and simplify.

Evaluate f(-2)

• 
  `f(x) = x^2 - 2x + 4`
• 
  `f(-2) = (-2)^2 - 2(-2) + 4`
• 
  `f(-2) = 4 + 4 + 4`
• 
  `f(-2) = 12`

The evaluated function is 12.

If this has been graphed, we can simply find f(-2) by looking at the y-values of intersection when x is -2.

Answer 2

Answer: C. 12

Explanation:

We will substitute -2 for x and solve.

Given:

F(x) = x² - 2x + 4

Substitute:

F(-2) = (-2)² - 2(-2) + 4

Square (-2):

F(-2) = 4 - 2(-2) + 4

Multiply -2 by -2:

F(-2) = 4 + 4 + 4

Add:

F(-2) = 12

C. 12
