See the answer AP CALCULUS AB 2012 SCORING GUIDELINES - College Board were asked to find the derivative f′()x. This involved correctly applying the chain rule to determine the symbolic derivative of f. Part (b) asked for an equation of the line tangent to the graph of f at the point where x =−3. Students needed to find the derivative at this point to determine the slope of the tangent line, the y-

To find f(x+h) we put (x+h) into the formula for the function instead of x. Example 1 . Differentiate the function f(x) = 2x2 + 4x. The sum, difference, product, or quotient of functions can be found easily. Sum: (f + g)(x) = f(x) In the following examples, let f(x) = 5x+2 and g(x) = x2-1. We will then The formula for the difference quotient is: [ f(x+h) - f(x) ] / h. If you go on to  x→a c = c. 2. lim x→a x = a. 3. lim x→a cf(x) = c lim x→a f(x). 4. lim x→a. [f(x) h( x) = 6.
