For the following functions, determine f(x), c, f ′(x), and f ′(c). Homework Help ✎

  1. This is Hana's Definition of the Derivative. Notice that Δx is equivalent to h.

    f(x) = 5 − 3x where c = 1
    so f '(x) = −3 and f '(1) = −3

  2. See hint in part (a).

  3. This is Ana's Definition of the Derivative.
