Which is which?
They both have an exponent and they are both functions right?
How can u tell?

f(x) = x^3
g(x) = 3^x
The exponential function is 3^x, because exponential functions have the form where the variable x is in the power, and not the base.
f(x) = x^3 is a polynomial, or a cubic.
Generally, exponential functions grow much faster than polynomials.

The exponential function is always the one with a constant raised to a variable, or, in this case, 3^x. The other one, where the variable is raised to the constant (x^3), is called a polynomial. If you were to graph x^3 and 3^x on the same graph, 3^x would have a much higher rate of increase. But yes, they both have exponents and they are both functions, but only 3^x is only an exponential function.

An exponential function has the dependent variable in the exponent, therfore g(x) is the exponential function. f(x) is just a polynomial (or more specifically and monomial) because x is raised to a power.

First you go to the local deli. They should have a good roast beef sammich. If not, you can eliminate y=mx+b
If they have a turkey club, then e+mc^2 may be the correct answer.
If you smoke pot - then you need to stop.
Good luck.

g(x)=3^x check the source at wikipedia:
