(−2,−2.99), (−1,−1.49), (0,0), and (1,1.49)


(−2,80), (−1,20), (0,5), and (1,1.25)


(−2,0.45), (−1,0.67), (0,1), and (1,1.50)


(−2,−2.5), (1,1.25), (0,0), and (1,1.2)

Answer 1

The multiple-choice answers match the function y = 5(1/4)^x (the original "14" was likely meant to be 1/4). Compute:

- x = −2: y = 5(1/4)^(−2) = 5·4^2 = 80
- x = −1: y = 5(1/4)^(−1) = 5·4 = 20
- x = 0: y = 5(1/4)^0 = 5
- x = 1: y = 5(1/4)^1 = 5/4 = 1.25

So pick: (−2,80), (−1,20), (0,5), (1,1.25). If the function truly was y = 5·14^x, none of the given choices match.
