Question

PLEASE HELP!!!

This table shows the input and output values for an exponential function f(x) .

What is the ratio of outputs for any two inputs that are one value apart?

A. 2
B. 4
C. -2
D. -1/2

Answer 1

A

Explanation:

We find the ratio by dividing two y-values from 2 consecutive x values (1 unit apart). Notice that in the table, all x-values are 1 unit apart. We can choose any pair of consecutive points.

Let's choose: (2,-4) and (1,-2). We divide -4/-2=+2.
