Example
Let us draw the graph of two polynomials
f(x) = 3x* + 2x³+ 7x? + 2x + 9 and
g(x) = 5x³ + 9x + 2
Create a script file and type the following code:
x = [-10 : 0.01: 10];
y = 3*x.^4 + 2 * x.^3 + 7 * x.^2 + 2 * x + 9;
g = 5
x.^3 + 9 * x + 2;
plot (x, y, 'r', x, 8, 'g')
When you run the file, MATLAB generates the following graph:
