Question

Which ordered pairs lie on the graph of the exponential function f(x)=−3^(x−1) +2 Select each correct answer.

​​ (−1,  2)

​ (1,  1) ​

​ (0,  0) ​ ​

​​ (4,−25) ​

Answer 1

(1, 1), (4, -25)

Explanation:

Answer 2

(1, 1), (4, -25)

Explanation:

You can evaluate the function to see.

f(-1) = -3^(-1-1)+2 = -3^(-2)+2 = -1/9 +2 ≠ 2

f(1) = -3^(1-1) +2 = -1 +2 = 1

f(0) = -3^(0-1) +2 = -1/3 +2 ≠ 0

f(4) = -3^(4 -1) +2 = -27 +2 = -25

_____

Or, you can graph the points and the curve.
