You can put this solution on YOUR website!
If f(x) = x 2 + 1 and g(x) = 3x + 1, find f(-1) + 5g(-3).
\n" ); document.write( "Do you mean f(x) = x^2 + 1 ?
\n" ); document.write( "Use ^(Shift 6) for exponents.
\n" ); document.write( "-----
\n" ); document.write( "f(x) = x^2 + 1
\n" ); document.write( "Wherever you see x, sub -1
\n" ); document.write( "f(-1) = (-1)^2 + 1 = 2
\n" ); document.write( "---
\n" ); document.write( "g(x) = 3x + 1
\n" ); document.write( "Sub -3
\n" ); document.write( "Multiply by 5
\n" ); document.write( "Add f(-1)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
