please solve questions and show all work in matlab code

Now let's use the MATLAB M-file in the text. You can use that as a starting point or write your own code following the pseudo-code provided. Write a MATLAB function y= func2 (x) which implements the equation f(x)=.9x2+1.7x+2.5=0. It will be used by the Newton-Raphson method M file. Use the MATLAB implementation of Newton-Raphson method to find a root of the function f(x)=.9x2+1.7x+2.5=0 with the initial guess x0=5. Perform the computations until percentage approximate relative error (a(%)) is less than a=2%. You are required to fill the following table. Repeat step 4 until percentage approximate relative error (a(%)) is less than s=0.2%
