Arandom sample of 36 trucks traveling on a section of an interstate showed an average speed of 71 mph. the distribution of speeds of all trucks on this section of highway is normally distributed with a standard deviation of 10.5 mph. the value to use for the standard error of the mean is:

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.
