Algebra.Com's Answer #358015 by mathie123(224)![]() ![]() ![]() You can put this solution on YOUR website! a) f(x)= -3x ,g(x)=2x+6\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "f(g(x)) is just basically saying everywhere you have an x in f(x), put the entire g(x) function.\r \n" ); document.write( "\n" ); document.write( "So for this example, f(g(x))=-3(2x+6)\r \n" ); document.write( "\n" ); document.write( "and g(f(x)) is just saying everywhere you have and x in g(x), put the entire f(x) function\r \n" ); document.write( "\n" ); document.write( "So for this example, g(f(x))=2(-3x)+6\r \n" ); document.write( "\n" ); document.write( "I will let you do b) yourself (hint: VERY similar to a), just different functions.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "_____________________________________________________________________ \n" ); document.write( "Hopefully this helps!
