Question:

- For problem 3: We did in class the following example to find an upper bound of x0: stepsome value input by the user x0some value input by the user x1 x0+ step; yo f(xo) y1 -f(x1) as long as yo> y1 (the function is still decreasing, so the minimum is still ahead) make another step x1Ex0+step yo f(xo) The loop stops when yoy1, and x1 is an upper bound of x0; the function starts increasing and minimum is now "behind" The following function f(x) 42a382 5x has a minimum on the interval [-2, 1]. Define xmin the location of that minimum. Using the search method presented in class, determine an upper bound of xmin, using the value of a variable step (to be obtained from the user)
