1.) (Fog)(x) f(x)=6x+13, g(x)=3x-1
\n" ); document.write( "(Fog)(x)= 6(3x-1)+13
\n" ); document.write( "(Fog)(x)= 18x-6+13
\n" ); document.write( "(Fog)(x)= 18x+7
\n" ); document.write( ".
\n" ); document.write( "2.) (Gof)(x) f(x)=-2x+8, g(x)=4x+7
\n" ); document.write( "(Gof)(x) = 4(-2x+8)+7
\n" ); document.write( "(Gof)(x) = -8x+32+7
\n" ); document.write( "(Gof)(x) = -8x+39
\n" ); document.write( ".
\n" ); document.write( "3.) For the functions f and g and the number c, compute fog (c)
\n" ); document.write( "F(x)=x^2+2x+5
\n" ); document.write( "G(x)=x^2+2x-1
\n" ); document.write( "C=3
\n" ); document.write( ".
\n" ); document.write( "fog(x) = (x^2+2x-1)^2+2(x^2+2x-1)+5
\n" ); document.write( "fog(c) = (c^2+2c-1)^2+2(c^2+2c-1)+5
\n" ); document.write( "fog(3) = (3^2+2(3)-1)^2+2(3^2+2(3)-1)+5
\n" ); document.write( "fog(3) = (9+6-1)^2+2(9+6-1)+5
\n" ); document.write( "fog(3) = (14)^2+2(14)+5
\n" ); document.write( "fog(3) = 229
\n" ); document.write( " \n" ); document.write( "
