Please help me!
A. 16
B. -11
C. 1
D. function is not defined for this value

Answer 1

B -11

Explanation f(-4) you find where f(-4) is possible. The only correct equation you can use for the piece wise is the top one 2x-3 because it says x is less then or equal to -4. Then you plug in -4 for x
F(-4)= 2(-4)-3
F(-4)= -8-3=-11
