1.)equation of the inverse?\r
\n" ); document.write( "\n" ); document.write( " $\"f%28x%29=3x%5E2%2B5\"$ \r
\n" ); document.write( "\n" ); document.write( "since $\"f%28x%29=y\"$ , we have\r
\n" ); document.write( "\n" ); document.write( " $\"y=3x%5E2%2B5\"$ .......swap $\"x\"$ and $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x=3y%5E2%2B5\"$ ............solve for $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"x-5=3y%5E2\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"%28x-5%29%2F3=y%5E2\"$ \r
