What are the domain and range for the exponential parent function, where b is a positive real number not equal to 1 and a > 0?
A. Domain: (-∞ , ∞); Range (-∞ , 0)
B. Domain: (-∞ , 0]; Range (-∞ , ∞)
C. Domain: (-∞ , ∞); Range (0 , ∞)
D. Domain: (0 , ∞); Range (-∞ , ∞)
please help
a*b^x
domain all reals
so it looks like A or C
double-checking, the range is all reals > 0
so, yep, it's still C
