Answer: Second Option

Step-by-step explanation:
The exponential growth functions have the following form:

Where a is the main coefficient, b is the base and x is the exponent.
For this type of functions the base b must always be greater than 1. Otherwise it would be an exponential decay function
Among the options given, the only function whose base is greater than 1 is the second option:

Answer:
a = 15
Step-by-step explanation:
This is your given:

You are going to want to get a alone to get what a equals.

Multiply 3 on both sides to get the a alone
