A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output. In this case, the equation

y = 2^x

is a function because for each value of

, there is only one corresponding value of

. Therefore, the equation

y = 2^x

represents a function.

\boxed{\text{Yes, } y=2^x \text{ is a function.}}
