How to plot x^3-4x^2+1 without setting the domain?

I need to specifically have matlab do the default domain first without inputting it as the first part of this problem, and my initial thought was to try this but it didn't work. I'm very new to matlab so it could be a simple mistake.

fplot(@(x) x.^3+4x.^2+1)

"4x" is not a valid expression. "4*x" is.

fplot(@(x) x.^3+4*x.^2+1)
