What are the domain and range for the exponential function f(x)=ab^x , where b is a positive real number not equal to 1 and a > 0? ! o domain: ( -∞,∞) ; range: (-∞,0) o domain: (-∞,0] ; range: (-∞,∞) o domain (-∞,∞) ; range: (0,∞) o domain (0,∞) ; range: (-∞,∞)

Domain (-∞,∞) ; range: (0,∞)

Step-by-step explanation:

1. The exponential functions with the form has domain of all real numbers, becaure there is no values in the set of real number for which the value of is not define. When approches to ∞, the function approches to ∞.

2. When approches to -∞, the function approches to 0 but never touches it. This means  that is always greater than zero (). Therefore, the range of the function is (0,∞).
