You can put this solution on YOUR website!
f(x) = 5x - 4
\n" ); document.write( "y = 5x - 4
\n" ); document.write( "x = 5y - 4
\n" ); document.write( "x + 4 = 5y
\n" ); document.write( "(1/5)x + 4/5 = y
\n" ); document.write( "(1/5)x + 4/5 = f^-1(x)
\n" ); document.write( "\"graph%28600%2C600%2C-10%2C10%2C-10%2C10%2Cx%2C5x-4%2Cx%2F5%2B4%2F5%29\"
