x = -pi:2*pi;
f(x) = (cos(2.*x));
plot (f)

x = -pi:2*pi;
f = cos(2.*x); % f(x) is wrong
plot(x, f)

e is not a defined constant. Use exp(x) to calculate e^x
Most likely you will also need element-wise division here:
h = (x^2-x+3)./(x-8);
% ^^
unless you really are trying to solve systems of linear equations.
