. Use the function y = 12(3)x to answer the questions.

What does the a value represent?
What is the a value a?


What does the b value represent?
what is the value of b?
Is it a growth or decay function?


What does the x value represent?

1 answer

The a value represents the initial value or starting point of the exponential function.

In the function y = 12(3)x, the value of a is 12.

The b value represents the rate of growth or decay.

In the function y = 12(3)x, the value of b is 3.

It is a growth function because the value of b is greater than 1.

The x value represents the input or the independent variable in the function. It can be any real number.
