Question

Describe the graphs of the functions f(x) = 2^x + 1 and g(x) = –2^x + 1. Compare and contrast the domain and range of f(x) and g(x).

Answer 1

the domain for both is same as the function is defined at all points of real line. so the domain can be any subset of real number. the range of the f(x) is 1 to +inf while the range of g(x) is -inf to +1.
