Algebra.Com's Answer #15812 by sdmmadam@yahoo.com(530)![]() ![]() ![]() You can put this solution on YOUR website! let f(x)=-2+3 and g (x)=x2 (x squared)\r \n" ); document.write( "\n" ); document.write( "I think f(x) is typed wrong. Either it should be f(x)=-2x+3 or f(x) =-2+3x \n" ); document.write( "1) let f(x) = -2x+3 ----(1) \n" ); document.write( "and g(x) = x^2 ----(2) \n" ); document.write( "f(g(3))= f[3^2] using (2) (putting x=3 in (2)) \n" ); document.write( "=f(9) \n" ); document.write( "=-2X9+3 = -18+3 = -15 \n" ); document.write( "Answer: f(g(3))=-15\r \n" ); document.write( "\n" ); document.write( "2) let f(x) = -2+3x ----(1) \n" ); document.write( "and g(x) = x^2 ----(2) \n" ); document.write( "f(g(3))= f[3^2] using (2) (putting x=3 in (2)) \n" ); document.write( "=f(9) \n" ); document.write( "=-2+3X9 = -2+27 = 25 \n" ); document.write( "Answer: f(g(3))= 25 \n" ); document.write( " |
