Question

What is the value of the expression f(–3)?
-15
3
-3
15

Answer 1

Option A, -15

Explanation:

Step 1: Look at the function that needs to be outputted when x = -3

Since x = -3, that means it falls into the first category of x ≤ -3

Step 2: Carry out the instructions

The function for the first category is
`-x^(2) + 2x`

`f(-3) =-(-3)^(2)+2(-3)`

`f(-3) = -(9) - 6`

`f(-3) = -15`

Answer: Option A, -15
