Determine if the equation y = 2^x represents exponential growth or decay

I thought at first it was growth but now I think it might be decay because there is no "b" in a parentheses so do I assume b is less than 1 so it's decay?

Please help

What happens if x > 1? What happens if x is negative or a fraction?

What does "b" have to do with this problem?
