5. Plot the functions r8 and 4 on the same graph, and determine how many times their graphs intersect. (Hint: You will probably have to make several plots, using various intervals, in order to find all the intersection points.) Now find the values of the points of intersection using the command fzero. (b) J(x +1) In z dr, dr, 0 1 (e) /V1+d. For this example, also compute the numerical value of the 0 integral
