Answer 1

The correct graph is the one that rises to the right, passes through (0,1), and approaches y = 0 on the left (the graph labelled C).

Properties:
- Domain: all real numbers (x ∈ (−∞, ∞)). (Select B.)
- Range: y > 0 (y ∈ (0, ∞)).
- y-intercept: (0, 1) because 2^0 = 1.
- Horizontal asymptote: y = 0 (the x-axis).
