The function represents the rate of flow of money in dollars per year. Assume a 10-year period and find the present value.f(x) = 0.5x at 2% compounded continuously
A. $21.90 B. $2478.10 C. $431.27 D. $43.80
Find the intervals on which the function is continuous.Is the function given by f(x) = 
continuous over the interval [-4, 4]? Why or why not?
A. Yes, f(x) is continuous at each point on [-4, 4] B. No, since f(x) is not continuous at x = 4
