the table represents an exponential function. what is the multiplicative rate of change of the function?\n|x|y|\n|1|3/2|\n|2|9/8|\n|3|27/32|\n|4|81/128|\no 2/3\no 3/4\no 4/3\no 3/2
Answer
Explanation:
Step1: Recall the formula for multiplicative rate of change
For an exponential function $y = a\cdot b^x$, the multiplicative rate of change is $b$. Given two - consecutive points $(x_1,y_1)$ and $(x_2,y_2)$ on the exponential function, $b=\frac{y_2}{y_1}$ when $x_2=x_1 + 1$.
Step2: Select two consecutive points
Let's take the first two points $(x_1 = 1,y_1=\frac{3}{2})$ and $(x_2 = 2,y_2=\frac{9}{8})$.
Step3: Calculate the multiplicative rate of change
$b=\frac{y_2}{y_1}=\frac{\frac{9}{8}}{\frac{3}{2}}=\frac{9}{8}\times\frac{2}{3}=\frac{3}{4}$
Answer:
$\frac{3}{4}$
