document.write( "Question 668382: Find the inverse of f(x)=2^x. Here is where I went with this. Change f(x) to y so it would read y=2^x. Interchange the y and x to get x=2^y. I don't know how to write this on here, but you would take the y square root of x and the y square root of 2^y to get y square root of x=2. This is where I get stuck. Thanks! \n" ); document.write( "
