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

  This relation represents a growth when b > 1 and a decay when b < 1.

Step-by-step explanation:

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.
