Please use the bisection method to find the zeros of this function in MATLAB

Consider the function f (x) = x 2x4 + 3x 2x + x 1 cos (50x). This function has at least one zero between x = -0.2 and x = 1.3. You can confirm this by calculating f(-0.2) and f(1.3) and checking that they have opposite signs. To make sure that you entered the function correctly, calculate the product f(-0.2) f (1.3) and save it in a variable called ans1. Use the bisection method (you can copy the code we wrote in class) to find a zero of f between a = -0.2 and b = 1.3. You should use exactly these values for a and b, and a tolerance of 10-1 (i.e., your final answer should be the first x you found such that 10-10
