(choose chapter or problem)

Write a user-defmed function that calculates the maximum (or minimum) of aquadratic equation of the form:l(x) = ax2+bx+cName the function [xI y I w] = maxormin (a I b I c) . The input arguments arethe coefficients a, b, and c. The output arguments are x, the coordinate of themaximum (or minimum); y, the maximum (or minimum) value; and w, whichis equal to 1 if y is a maximum and equal to 2 if y is a minimum.Use the function to determine the maximum or minimum of the followingfunctions:(a) l(x) = 3xL 7x + 14 (b) l(x) = - 5x2 -llx + 15
