A quadratic function is given below:
\n" ); document.write( "f(x)=3x^2-x+6
\n" ); document.write( "What is f(2)?
\n" ); document.write( "A. 40
\n" ); document.write( "B. 28
\n" ); document.write( "C. 16
\n" ); document.write( "D. 4
\n" ); document.write( ".
\n" ); document.write( "f(x)=3x^2-x+6
\n" ); document.write( "f(x) is a \"function of x\" -- meaning for a particular value of x you can find the value of f(x).
\n" ); document.write( "In your case, when they say \"what is f(2)\"? They are asking you what the value of f(x) when x=2. So, simply plug in the value of 2 for x and solve:
\n" ); document.write( "f(x)=3x^2-x+6
\n" ); document.write( "f(2)=3(2^2)-2+6
\n" ); document.write( "f(2)=3(4)-2+6
\n" ); document.write( "f(2)=12-2+6
\n" ); document.write( "f(2)=10+6
\n" ); document.write( "f(2)=16
\n" ); document.write( "
\n" );
