What have you done so far? What specific problems are you having with your code? Do you know how to evaluate polynomials for a vector input? Do you know how to plot?

See the documentation on Anonymous Functions (link) and the linspace (link) function.

x = linspace(-10,10);
f = 5*x.^2+9*x+2;
G = 3*x+12;
plot(x,f,'r-',x,G,'g-')
