You can put this solution on YOUR website!
f(x) = –4x – 4, find f(2)
\n" ); document.write( " f(2) = –4x – 4 [let x=2 and solve]
\n" ); document.write( " f(2) = –4(2) – 4
\n" ); document.write( " f(2) = -8 – 4
\n" ); document.write( " f(2) = -12
\n" ); document.write( "So, when x=2, y=-12
\n" ); document.write( ".
\n" ); document.write( "check by plugging in the values of x and y and solving
\n" ); document.write( "-12 = –4(2) – 4
\n" ); document.write( "-12 = -8 – 4
\n" ); document.write( "-12=-12 [checks out] \n" ); document.write( "

\n" );
