(1) d

(2) b

(3) a

(4) c

(5) e

Step-by-step explanation:

The given problem is incomplete. Find the attachment of the full question.

According to the question,

(1)

By putting x = -2, we get

f(x)=(-2)^3-5

       =-8-5

       =-13

(2)

By putting x = 0, we get

f(x)=(0)^3-5

       =0-5

       =-5

(3)

By putting x = 3, we get

f(x)=8

(4)

By putting x = 9, we get

f(x)=(2)^{9-7}

       =(2)^2

       =4

(5)

By putting x = 11, we get

f(x)=(2)^{11-7}
