Module 4 1. what is the rational exponent property? also give an example of when it is used. 2. give an example of when you would use use f(x) = a(b)^x. 3. give an example of when you would use use f(x) = p(1+r)^x. 4. what is the growth rate of the function f(x) = 15(1.09)^x? 5. what is the rate of decay of the function f(x) = 10(0.74)^x? 6. find the average rate of change for the f(x) = 7(1.02)^x for x = 3 to x = 5.
