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 [tex]-x^{2} + 2x[/tex]

[tex]f(-3) =-(-3)^{2}+2(-3)[/tex]

[tex]f(-3) = -(9) - 6[/tex]

[tex]f(-3) = -15[/tex]

Answer:  Option A, -15
