A.
–40

Answer 1

They both have the same notation so you can just say f(-4) where the -4 will be plugged into the x values so if you plug in -4 for the x values you get?

Answer 4

Yeah?

Answer 5

F(x) that -4 is going into that x part f(-4) so this is saying find the value of the equation when x is -4
