Consider the following function as show in the figure below:

Write a script that uses the bisection function to estimate both roots $($crossings$)$ of the function. Assume that a $=11\mathrm{.}7,$ b $=8\mathrm{.}8,$ c $=0\mathrm{.}9,$ and d $=14.$ Determine your own initial guesses. Continue until the approximate relative percent error falls below $0\mathrm{.}001\%.$

Requirements:

Create an anonymous function you will use to solve this problem.

Assign the variable root$1$ to the first solution of the problem closest to the origin.

Assign the variable root$2$ to the second solution of the problem furthest from the origin.
