How can I plot the function y = e^(-2x^2) * cos(4pi*x - 1.5)?

How do I plot the function of y = e^(-2x^2) * cos(4pi*x - 1.5)? This is what I have so far but I can't seem to figure out what to do for the x coordinate. Is my y correct? Please help!

x=?

y=exp(-2.*x.^2) .* cos(4.*pi.*x - 1.5)

plot(x,y)

Pick a range for x. E.g.,

x = 0:0.01:2;
y = exp(-2.*x.^2) .* cos(4.*pi.*x - 1.5);
plot(x,y)

Thank you! I was entering an incorrect range. This solved my issue.
