An exponential function is expressed in the form y= ab^x. This relation represents a growth when and a decay when __.

Answer 1:

- b>1
- 0 - b is positive
- b is negative
- a > 1
- 0
Answer 2:

- b>1
- 0 - b is positive
- b is negative
- a > 1
- 0

The previous value of y is multiplied by b when x increases by 1. In order for the product to be greater than the previous value (growth), the value of b must be greater than 1.

In order for the product to be smaller than the previous value (decay), the value of b must be less than 1.

_____

Comment on the nature of the function

In order for the function value to remain positive, both "a" and "b" must be greater than zero.

An exponential function is expressed in the form y= ab^x. This relation represents a growth when ____ and a decay when ______. Answer 1: - b>1 - 0 - b is positive - b is negative - a > 1 - 0 Answer 2: - b>1 - 0 - b is positive - b is negative - a > 1 - 0
