Consider the following function:
Y = -0.865 + 8.454X - 1.696X2 + 0.132X3 - 0.00331X4
a. Plot this function on an X-Y graph for positive values of X from 1 to 20.
b. How many local maximum solutions are there?
c. How many local minimum solutions are there?
d. Use Solver to find the maximum value of Y using a starting value of X = 2. What value of Y do you obtain?
e. Use Solver to find the maximum value of Y using a starting value of X = 14. What value of Y do you obtain?
