Find the inverse of the function: y = \"%283x+%2B+9%29%2F12\"
\n" ); document.write( "Swap x and y and solve for y
\n" ); document.write( "x = \"%283y+%2B+9%29%2F12\"
\n" ); document.write( "multiply both sides by 12
\n" ); document.write( "12x = 3y + 9
\n" ); document.write( "12x - 9 = 3y
\n" ); document.write( "divide all terms by 3
\n" ); document.write( "4x - 3 = y
\n" ); document.write( ":
\n" ); document.write( "y = 4x - 3 is the inverse
\n" ); document.write( "
\n" );
