Hi!
If i have f(x) = 1 + x and g(x) = 1 - x, i want to find h(x) = f(x)*g(x) = (1+x)*(1-x)=1-x.^2 What should i do?
Thanks!

It looks like you already did it. To code it using anonymous functions:
f = @(x) 1 + x;
g = @(x) 1 - x;
h = @(x) f(x).*g(x);
x = linspace(-10, 10);
figure(1)
plot(x, f(x), x, g(x), x, h(x))
grid
legend('f(x)', 'g(x)', 'h(x)', 'Location', 'south')
