Question

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? Help please!

O domain: ( -∞,∞) ; range: (-∞,0)
O domain: (-∞,0] ; range: (-∞,∞)
O domain (-∞,∞) ; range: (0,∞)
O domain (0,∞) ; range: (-∞,∞)

    Answer: Domain (-∞,∞) ; range: (0,∞)

    Step-by-step explanation:

    1. The exponential functions with the form f(x)=ab^{x} has domain of all real numbers, becaure there is no values in the set of real number for which the value of x is not define. When x approches to ∞, the function approches to ∞.

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