Question

Find the first 3 iterates of the function f (x) = x - 4 when Xo = -11.

-11, -15, -19
-7, -3,1
-4,-8, -12
-15.-19.-23

Answer 1

D) -15, -19, -23

Step-by-step explanation:

`X_0=-11`

`X_1=(-11)-(-4)=-15`

`X_2=(-15)-(-4)=-19`

`X_3=(-19)-(-4)=-23`

Answer 2

Answer: Choice A

-11, -15, -19

================================================

Step-by-step explanation:

Plug x = -11 into the function.

f(x) = x-4

f(-11) = -11-4

f(-11) = -15

The output -15 is now the input to set up the next iteration.

f(x) = x-4

f(-15) = -15-4

f(-15) = -19

The first three iterates are -11, -15, -19
