ANSWER

Exponential growth

Step-by-step explanation

We want to identify if the given function is an exponential growth or decay function:


y=(2)^x

An exponential function is given generally as:


y=a(b)^x

where a = initial amount

b = exponential factor

For an exponential function, when b is greater than 0 or less than 1, the function is a decay function while when b is greater than 1, it is a growth function.

The given function has an exponential factor of 2. This is greater than 1.

Hence, the function is an exponential growth function.
