This must be solved with MATLAB.

3. One method for finding a root of a function is the bisection method. Here is a nice writeup on the bisection method: http://www.mathwarehouse.com/calculus/continuity/continuity-bisection-method.php Write a function bisect() that finds the root of a polynomial ax3+bx2+cx+d over an interval (A,B). The function takes as input the coefficients a, b, c, d, and the interval limits A and B. You can assume that there are either no roots or one root in the interval [A,B]. The function returns as output the value of the root over the interval (A,B), if it exists. The function also returns as output a message (flag) that informs the user if no roots exist over the interval [A,B). It should be clear that you cannot use any of MATLAB's built-in root finding functions to do this problem. Use the bisection method. a = -1; b = 1; C = -1; d = 10; A = 0; B = 5; [root, flag] = bisect(a,b,c,d, A,B)
