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(3.75)^x
• f(x) = 417(0.0375)^x
• f(x) = 417(1.0375)^x
• f(x) = 417(1.375)^x

The function to find the value of a car after t years is given by v(t) = 24,000(.75)^t Which of the following statements is not true?

• The starting value of the car was $24,000.
• The y-values of the graph increase as the x-values increase.
• The value of b indicates this is an exponential decay situation.
• The horizontal asymptote is y = 0, which means the car will never have a value of $0.
