A function is given Determine the average rate of change of

A function is given. Determine the average rate of change of the function between the given values of the variable. h(t) = t^2 + 5t; t = -1, t = 2 A function is given below. Determine the average rate of change of the function between the given value of the variable. g(x) = 9/x; x = 2, x = a

Solution

2) h(t) = t^2 + 5t

Average rate of change = [h(2) - h(-1)] /(2 + 1) = [14 + 4]/3 = 18/3

3) Average rate of change = [g(a) - g(2)] /(a - 2)

= [9/a – 9/2]/(a - 2)
= (9/2a)*(2 - a)/(a - 2) = -9/2a
