The answer is A because when y = 3^x is graphed the equation stays steady until -2 on the x plane then rapidly shoots up.

Answer:

A.
y=3^x

Explanation:

We are asked to find the exponential growth function from our given choices.

We know that an exponential function is in form
y=a\cdot b^x, where,

a = Initial value,

b = For exponential growth
b>1.

Upon looking at our given choices, we can see that option A is the correct choice, where,
a=1 and
b>1 that is 3.
