To find the inverse of a function, there are TWO steps:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 1: Given that y =4x+2, INTERCHANGE the x and y.
\n" ); document.write( "x=4y+2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Step 2: SOLVE for y.\r
\n" ); document.write( "\n" ); document.write( "x=4y+2
\n" ); document.write( "x-2=4y
\n" ); document.write( "4y=x-2\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide both sides by 4:
\n" ); document.write( " $\"y=%28x-2%29%2F4\"$ or $\"y=%28x%2F4%29-%281%2F2%29\"$ \r
\n" ); document.write( "
