Question

the table represents an exponential function.
what is the multiplicative rate of change of the
function?

x	y
2	0.125
3	0.0625
4	0.03125

\bigcirc 0.2
\bigcirc 0.25
\bigcirc 0.5
\bigcirc 0.75

Explanation:

Step1: Divide y2 by y1

$\frac{0.125}{0.25} = 0.5$

Step2: Verify with next y-values

$\frac{0.0625}{0.125} = 0.5$, $\frac{0.03125}{0.0625} = 0.5$

Answer:

0.5
