| 4. Graph the function spike(x) = 3x2 4 + 2. Find an appropriate window for fandfprime for spike. a. There are two values of x for which the derivative does not exist. What are these values, and why does the derivative not exist there? b. Find the derivative off at those values of x where it exists, and add it to the Plot window. c. Look at your plot. Does your statement(s) from Problem 3 still hold? Do you need to make any modifications? If so, make your additions or corrections below
