19. VISITORS The number of visitors to a new skateboa the exponential function g(x) = 20(2*), where x repr since the park's grand opening. Explain how the nur first month is a dilation of the parent function Ax) = :20. DEPRECIATION Depreciation is the decrease in the value of an item resulting from its age or wear. When an item loses about the same percent of its value each year, an exponential function can be used to model its decreasing value over time. The function g(x) = 12,000(0.85) can be used to model the value of a $12,000 car as it depreciates at an annual rate of 15% over x years. g(x) is a dilation of the parent function f(x) = 0.85*. The graph shows the function g(x).
