A shipping company started with 40 employees. The number of employees in the shipping company increases at a rate of 7.5% each year. What function can be used to model the number of employees, f(x), in the shipping company after x years?

$f\left(x\right)=40\left(1.075\right)^x$

$f\left(x\right)=43\left(1.075\right)^x$

$f\left(x\right)=40\left(.075\right)^x$

There were 417 cell phones sold at an electronics store in January. Since then, cell phone sales at this store have increased at a rate of 3.75% per month. At this rate of growth, which function can be used to determine the monthly cell phone sales x months after January?

$f(x)=417(1-0.0375)^x$

$f(x)=417(1-3.75)^x$

$f(x)=417(1+0.0375)^x$

$f(x)=417(1+3.75)^x$
