Hi there,
\n" ); document.write( "Substitute x = 2 into f(x)
\n" ); document.write( "f(x) = 4x^3 + 7x^2 - x + C
\n" ); document.write( "f(2) = 4(2)^3 + 7(2)^2 - 2 + C
\n" ); document.write( "f(2) = 32 + 28 - 2 + C
\n" ); document.write( "f(2) = 58 + C
\n" ); document.write( "Given f(2) = 1
\n" ); document.write( "58 + C = 1
\n" ); document.write( "C = 1 - 58
\n" ); document.write( "C = -57
\n" ); document.write( "Hope this helps :-) \n" ); document.write( "
