One Way:
\n" ); document.write( "f(x) = 3x - 2
\n" ); document.write( "f(x) = 3(x^2 + 1) - 2
\n" ); document.write( "f(x) = 3x^2 + 1
\n" ); document.write( "f(3) = 3*9 + 1 = 28
\n" ); document.write( "Another Way:
\n" ); document.write( "g(3) = 3^2 + 1 = 10
\n" ); document.write( "f(10) = 3*10 - 2 = 28
\n" ); document.write( "Answer: 28 \n" ); document.write( "
