Question

This is part 1 of a 4 part MATLAB question. In this part, you are to upload a scan of your handwritten notes.

Start with EITHER your WA09A working code and your WA09B code. Modify the code so that you build an array that is plotted for f(x) and g(x). Use the following:

x = 3.2 : 0.01 : 3.7

To plot the following two equations:

f(x) = 3x³ - 4x² + 1 and g(x) = 6x² + 2x - 2

You will need to relook at lesson Introduction to MATLAB on plotting.

To answer this part of WA09C - upload a scan of your Handwritten notes.

WA09A Code

clear;clc

for x = 1:16
    y(x) = -2 * (0.1*x^2 - 2*x + 1);
end
y
