1. a) Create a MATLAB function called "Funl" to evaluate the function above for a given value of x . Write the MATLAB code here: b) Use the fplot command to graph the function for x values from 0 to 3 . Show the fplot command below, and sketch the shape of the curve below (note: you might want to turn on the grid for the MATLAB plot): c) Based on the curve, how many roots of the equation are there between 0 and 3 ? What are the approximate values of those roots? d) Use Excel's Goal Seek to find the roots to three decimal places.
