Part 1: The derivative at a specific point Use the definition of the derviative to compute the derivative of f(a) = 1 - 7a at the specific point a = 2. Evaluate the limit by using algebra to simplify the difference quotient (in first answer box) and then evaluating the limit (in the second answer box). f' (2) = lim f (2 + h) - f(2) lim h-+0 h h +0
