Algebra.Com's Answer #644846 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! f(x)= x-12/5 is shown. \n" ); document.write( "Which expression is equivalent to g(x) in the equation f(g(x))=x \n" ); document.write( "----- \n" ); document.write( "Since f[g(x)] = x , g(x) is the inverse of f(x). \n" ); document.write( "----- \n" ); document.write( "Determine the inverse of f(x):: \n" ); document.write( "1st:: Interchange x and y to get:: x = y-12/5 \n" ); document.write( "2nd:: Solve for \"y:: y = 5x+12 \n" ); document.write( "------------------\r \n" ); document.write( "\n" ); document.write( "a.) -5/x-12 \n" ); document.write( "b.)5/x-12 \n" ); document.write( "c.)5x-12 \n" ); document.write( "d.)5x+12 \n" ); document.write( "---------------- \n" ); document.write( "Ans: d \n" ); document.write( "------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "------------ \n" ); document.write( " |
