You can put this solution on YOUR website!
g(x) = 1-2x
\n" ); document.write( "g(x+h) = 1-2(x+h) = 1 - 2x - 2h
\n" ); document.write( "g(x+h)-g(x) = (1 - 2x - 2h) - (1 - 2x)
\n" ); document.write( "Note the use of parentheses. When you substituting in more than one term, it is important to use parentheses. Simplifying we get:
\n" ); document.write( "g(x+h)-g(x) = (1 - 2x - 2h) - (1 - 2x) = -2h
\n" ); document.write( " $\"%28g%28x%2Bh%29-g%28x%29%29%2Fh+=+%28-2h%29%2Fh+=+-2\"$ \n" ); document.write( "

\n" );
