Question

What is the range of  g(x)= e^x

Answer 1

g(x) = e^x . The domain is the set of all real numbers. Now taking log on both sides, we get lny=x. Now logarithm function is only valid for all real numbers greater than 0. Thus the values of 'y' include all real numbers greater than 0.
Hence range of g(x) is R⁺ or (0,∞).
