Question

Describe the graphs of the functions f(x) = 2^x – 3 and g(x) = –2^x – 3. Compare and contrast the domain and range of f(x) and g(x).

Answer 1

both are exactly the same shape but they're reflections of each other over the line y=-3
domain for both: (-inf, -3)
range for f: (-3, inf)
range for g: (-inf, -3)

Answer 2

Would the domain for both be considered all real numbers?
