Given f(x)=4x-3 and g(x)=2x^2-5 find f[g(-1)] and g[f(-1)].
\n" ); document.write( "g(-1) = 2(-1)^2-5 = 2 - 5 = -3
\n" ); document.write( "f(-3) = 4(-3)-3 = -15
\n" ); document.write( "f[g(-1)] = -15
\n" ); document.write( "f(-1) = 4(-1)-3= -7
\n" ); document.write( "g(-7) = 2(-7)^2-5 = 2(49)-5 = 93
\n" ); document.write( "g[f(-1)] = 93 \n" ); document.write( "

\n" );
