Create a program to code the bisection method. Use the example f(x) = x3 – 3x – 4 with your left starting value of 1 and your right starting value of 3. Your program should end when |fmid| < TOL where TOL = 0.01. Count how many times it took for the bisection to run before it finishes with your answer.To evaluate f(x) you must use a function call.
