To find the inverse of a function, replace f(x) with y.
\n" ); document.write( " $\"y=4x-3\"$
\n" ); document.write( "The next step is interchange y for x and vice versa.
\n" ); document.write( " $\"highlight%28x%29=4%2Ahighlight%28y%29-3\"$
\n" ); document.write( "Then solve for y.
\n" ); document.write( " $\"x=4y-3\"$
\n" ); document.write( " $\"4y=x%2B3\"$
\n" ); document.write( " $\"y=%28x%2B3%29%2F4\"$
\n" ); document.write( "The inverse of f(x),
\n" ); document.write( " $\"f%5E%28-1%29%28x%29=%28x%2B3%29%2F4\"$ \n" ); document.write( "
