Answer 1

The function is y = 5(1/4)^x. Evaluate at each x:

- x = −2: y = 5(1/4)^(−2) = 5·4^2 = 5·16 = 80 → (−2, 80)
- x = −1: y = 5(1/4)^(−1) = 5·4 = 20 → (−1, 20)
- x = 0: y = 5(1/4)^0 = 5·1 = 5 → (0, 5)
- x = 1: y = 5(1/4)^1 = 5·0.25 = 1.25 → (1, 1.25)

Answer: (−2,80), (−1,20), (0,5), (1,1.25).
