(c) wrnte the qdai xp and x (d) Solve for the x-intercept of the line in equation (c). What formula have you derived, with what roles for p, q, and x? 2. Use MATLAB to plot the function f(x) (5-x) exp(x)-5, for x between 0 and 5. (This function is associated with the Wien radiation law, which gives a method to estimate the surface temperature 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 10-5 that contains the root, so that the midpoint of this interval is wit 5 x 10-7 of the root). At each step, print out the endpoints of the smallest interval known to contain a root. Without running the code further, answer the following: How many steps would be required to reduce the size of this interval to 10-12? Explain your answer (b) Write a routine to use Newton's method or use routine newton available from the book's web page to find a root of f(x), using initial guess x0 5. Print out your approximate solution xe and the value o of f(ak) at each step and run until I faxe) s 10-8. Without running the code further, but perhaps using information from your code about the
