What are the domain and range of the function f(x) = 4(RootIndex 3 StartRoot 81 EndRoot) Superscript x?

{x| x is a real number}; {y| y > 0}
{x| x > 4}; {y| y > 0}
{x| x is a real number}; {y| y > 4}
{x| x > 4}; {y| y > 4}



Answer :

{x| x is a real number}; {y| y > 0}

This is the correct answer. The domain is all real numbers, and the range is all positive real numbers due to the nature of the exponential function.
