Answer:
Explanation:
Let f(x) be our exponential growth function representing growth after x years.
We are asked to find the exponential function that satisfies the given conditions: Initial value = 33, increasing at a rate of 7% per year.
Since an exponential growth function is in form:
, where a= initial value of function and r = growth rate in decimal form.
Given:
a=33
r=7%.
Let us convert our given rate in decimal form.
![7\text{ percent}=(7)/(100)=0.07](https://img.qammunity.org/2019/formulas/mathematics/high-school/7juc85csee74yn5lt6a6mfew68n41liup0.png)
Now let us substitute our given values in exponential function form:
![f(x)=33*(1+0.07)^x](https://img.qammunity.org/2019/formulas/mathematics/high-school/2cd0v1k0hi47yo1edui3qxa82jzn0rrwpc.png)
![f(x)=33*(1.07)^x](https://img.qammunity.org/2019/formulas/mathematics/high-school/4netojakowl9qzl85m0dzaxavb7a1rqxyt.png)
Therefore, the exponential function that satisfies our given conditions will be
