Find the inverse of the function \n" ); document.write( "f(x) = 8/(x + 8) \n" ); document.write( "--------- \n" ); document.write( "y = 8/(x+8) \n" ); document.write( "============== \n" ); document.write( "x = 8/(y+8) ----- solve for y \n" ); document.write( "x*(y+8) = 8 \n" ); document.write( "y+8 = 8/x \n" ); document.write( "y = (8/x) - 8 \n" ); document.write( "Your answer is correct, but it can be converted to #2 \n" ); document.write( "Y = (8-8x)/x \n" ); document.write( "y = (-8x+8)/x \n" ); document.write( " \n" ); document.write( " |
