y=(5x^4 + 5^x -1)/(2x^3 +1)

More specifically is 5^x a valid term in a polynomial?

It is not.

A rational function is defined as the quotient of two polynomials functions. Like you said, 5x is not a valid term of a polynomial.

gb7nash,

there is no "like you said," because the OP didn't state that 5^x isn't
a valid term of a poynomial. He asked if it was.
...and gb7nash answered him. Is this really something to nitpick about?
