arlik [135]

Answer:

Option A, -15

Step-by-step 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
