Is it possible to include a case distinction in a symbolic expression?

More precisely, I'm currently trying to understand how to include a truncated power function into a symbolic expression, if that is at all possible.

To distinct two cases you can use the heaviside function:

f(x) = heaviside(x)*x^2
print type(f)
f(2); f(0); f(-2)
