The function c(x) = 72. (1.04) models the cost in dollars, c, of 1 ounce of a certain chemical used in a laboratory. x represents the number of years since 2010. By what percentage per year does the cost of the chemical change over time?​

ANSWER:4%

A. plot the data for the functions f(x) and g(x) on a grid and connect the points. x -2 -1 0 1 2 f(x) 1/9 1/3 1 3 9 x -2 -1 0 1 2 g(x) -4 -2 0 2 4 b. which function could be described as exponential and which as linear? explain. c. if the functions continue with the same pattern, will the function values ever be equal? if so, give estimates for the value of x that will make the function values equals. if not, explain why the function values will never be equal.
