Answer:
The multiplicative rate of change of the function is
Step-by-step explanation:
You are given the table
An exponential function can be written as
where b is the multiplicative rate of change of the function.
Find a and b. Substitute first two corresponding values of x and y into the function expression:
Divide the second equality by the first equality:
Substitute it into the first equality:
So, the function expression is
Check whether remaining two values of x and y suit this expression:
So, the multiplicative rate of change of the function is
