Let f(x)=x^2-2. Evaluate f(x+h)-f(x)/h for some nonzero constant h. You must show work. \r
\n" ); document.write( "\n" ); document.write( "Okay so this is what I did, correct me if I am wrong\r
\n" ); document.write( "\n" ); document.write( "f(x)= ((x^2-2)+h)-x^2-2/h can someone help me with the rest?
\n" ); document.write( "========================
\n" ); document.write( "f(x)=x^2-2
\n" ); document.write( "Sub x+h for x
\n" ); document.write( "f(x+h) = (x+h)^2 - 2
\n" ); document.write( "= x^2 + 2hx + h^2 - 2
\n" ); document.write( "-------------
\n" ); document.write( "f(x+h)-f(x)/h = $\"%28%28x%5E2+%2B+2hx+%2B+h%5E2+-+2%29+-+%28x%5E2-2%29%29%2Fh\"$
\n" ); document.write( "= $\"2hx%2Fh\"$
\n" ); document.write( "= 2x \n" ); document.write( "

\n" );
