Question

What is f(0) given f(x) = 5(x + 2)2 - 10? ​

Answer 1

10

Explanation:

`f(x) =5(x+2)^2 -10\\\\f(0) = 5(0+2)^2 -10\\\\= 5(2)^2-10\\\\5(4)-10\\\\20-10\\\\f(0) =10`

Answer 2

Answer: C) 10

Work Shown:

The idea is to replace x with 0 and then use PEMDAS to simplify.

f(x) = 5(x+2)^2 - 10

f(0) = 5(0+2)^2 - 10

f(0) = 5(2)^2 - 10

f(0) = 5(4) - 10

f(0) = 20-10

f(0) = 10
