Answer 1

Answer:

A and B

Step-by-step explanation:

assuming the function should be

- $3^{x-1}$ + 2, then

A

substitute the x value into f(x) and check the validity of the y- value

f(4) = - $3^{3}$ + 2 = - 27 + 2 = - 25 ← agrees with y value

(4, - 25) lies on the graph

B f(1) = - $3^{0}$ + 2 = - 1 + 2 = 1 ← agrees with y value

(1, 1) lies on the graph

C

f(- 1) = - $3^{-2}$ + 2 = - $\frac{1}{9}$ + 2 ≠ 2

(- 1, 2) does not lie on the graph

D

f(0) = $3^{-1}$ + 2 = - $\frac{1}{3}$ + 2 ≠ 0

(0, 0) does not lie on the graph
