document.write( "NB- i think it's not a function because input 5 will give no output .but the domain of the function doesn't say anything about 5. if A WOULD BE R-{5} THEN IT WOULD BE A FUNCTION. I AM NOT SURE About it. what does A⊂R INDICATE HERE.HENCE WILL INVERSE BE POSSIBLE ? \n" );

Algebra.Com's Answer #658592 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! f(x)= (1-2x)/(x-5) is a FUNCTION. FIND IT'S INVERSE. \n" ); document.write( "1st:: Interchange x and y to get: \n" ); document.write( "x = (1-2y)/(y-5) \n" ); document.write( "------- \n" ); document.write( "2nd:: Solve for \"y\":: \n" ); document.write( "xy-5x = 1-2y \n" ); document.write( "------ \n" ); document.write( "2y+xy = 5x+1 \n" ); document.write( "y(2+x) = (5x+1) \n" ); document.write( "y = (5x+1)/(x+2) \n" ); document.write( "----------- \n" ); document.write( "That is the inverse. \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "------- \n" ); document.write( " |
