  1. Hanah wrote this derivative function: Homework Help ✎

    1. What is f(x) ?

    2. What is f ′(x) ? (Note--Avoid the algebra by using the Power Rule.)

    3. Use your slope function to find f ′(0) and f ′( l ).

Hanah's (symmetrical difference) definition of the derivative;

f(x) = x2 − 3

Find f '(x), which is also the value of the limit.

Power Rule
if f(x) = xn
then f '(x) = nxn − 1

f(x) = x2 − 3
f '(x) = __________

Evaluate.
