Question

Please answer ASAP: Which of the following represent an exponential growth function?

y = 3^x
y=(1/3)^x
y=3x
y=1/3x

Answer 1

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 2

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.
