Question

Determine which of the explicit rules represent the table of values. Select all that apply.

Answer 1

A. f(x) = 0.8 (5)ˣ

Explanation:

This is the only one that fits the x and f(x) values

x 0.8 (5)ˣ

------------------------------------------------------

1 0.8 x 5¹ = 0.8 x 5 = 4

2 0.8 x 5² = 0.8 x 25 = 20

3 0.8 x 5³ = 0.8 x 125 = 100

4 0.8 x 5⁴= 0.8 x 625 = 500

The others will not eve yield proper results for x = 1, you can try them out
