The number of stores opened by a coffee company can be modeled by the exponential function graphed on the grid, where x is the number of years since 1992. Based on the graph, which statement does NOT appear to be true?

• The coffee company had opened 400 stores by the end of 1992.

• The coffee company opened 100 stores in one year.

• Every year the number of stores the coffee company opened increased by 25%.

• Since 1992 the coffee company has opened 250 stores each year.

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
