\n" ); document.write( "f(x) = y, so write the equation
\n" ); document.write( "y = 4/x
\n" ); document.write( "To find the inverse, swap x and y and solve for y
\n" ); document.write( "x = 4/y
\n" ); document.write( "Multiply both sides by y
\n" ); document.write( "xy = 4
\n" ); document.write( "divide both sides by x
\n" ); document.write( "y = 4/x, which means the inverse is the same as the original equation
