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(1.375)*
f(x) = 417(3.75)
f(x) = 417(0.0375)*
