Algebra.Com's Answer #58315 by SMM52091(3)![]() ![]() ![]() You can put this solution on YOUR website! In order to find g(f(2)), just find f(2) and then g() it. For example...\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the question asks for g(f(2)). Since f(2) equals 2, then g(f(2)) is the same thing as g(2). Now apply the g formula.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So g(f(2)) = 0. \r \n" ); document.write( "\n" ); document.write( "Now just because g(f(2)) equals 0 doesnt mean f(g(2)) equals 0. You need to redo it for the second problem, just in a different way. Find g(2) and then f() it.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Since g(2) = 0, then f(g(2)) is the same thing as f(0). So find the function of 0 with the f(x) formula.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So f(g(2)) = 0 \n" ); document.write( "Hope I could help \n" ); document.write( " |
