2. Use MATLAB to plot the function f(x) - (5 - x) exp(x)-5, for x between O and 5. (This function is associated with the Wien radiation law, which gives a method to estimate the surface tempera- ture of a star.) (a) Write a bisection routine or use routine bisect available from the book's web page to find a root of f(x) in the interval [4, 5], accurate to six decimal places (i.e., find an interval of width at most 10 that contains the root, so that the 7 midpoint of this interval is within 5 x 10 of the root). At each step, print out the end- points of the smallest interval known to con tain a root. Without running the code further, answer the following: How many steps would be reguired to reduce the size of this interval to 12 10?Explain your
