You are plotting just one point at the end, with coordinates (maxiter + 1, x(maxiter + 1)).

If you want to plot $g(x)$, you should do something like this (for example before calculating the fixed-point):

x= -10:0.01:10;
g = x^5-3*x^3-2*x^2+2;
plot(x, g);

After this, you should calculate the fixed-point. If you call it $x$ in your code, you can do the following after the fixed-point iteration:

hold on;
fixed_g = x^5-3*x^3-2*x^2+2;
plot(x, fixed_g, 'o');

g = x^5-3*x^3-2*x^2+2;

I got an error .
