What is the multiplicative rate of change of the function

mario62 [17]

Answer: B $\frac{2}{3}$

Step-by-step explanation:

From the given table

When x changes from 1 to 2 , value of y changes from 6 to 4

The multiplicative rate of change= $\frac{4}{6}=\frac{2}{3}$

Similarly we can check

When x changes from 2 to 3 , value of y changes from 4 to $\frac{8}{3}$

The multiplicative rate of change= $\frac{\frac{8}{3}}{4}=\frac{2}{3}$

When x changes from 3 to 4 , value of y changes from $\frac{8}{3}$ to $\frac{16}{9}$

The multiplicative rate of change= $\frac{\frac{16}{9}}{\frac{8}{3}}=\frac{2}{3}$

Therefore, the multiplicative rate of exponential function = $\frac{2}{3}$
