Conjecture a formula for f'(a) that depends only on the value a. That is, in the same way that we have a formula for f(x) (recall f(x) = 4x - x2), see if you can use your work above to guess a formula for f'(a) in terms of a.

Please answer only option c. I’ll also write the results of option a and b and upload the formula in option a. You can use them if you need. f’(0) = 4 f’(1) = 2 f’(2) = 0 f’(3) = -2 f’(4) = -4 f’(5) = -6 f’(a) = 2(2-a) (formula in option b)

Preview Activity 1.4.1. Consider the function f(x) = 4x – x².
a. Use the limit definition to compute the derivative values: f'(0), f'(1), f'(2), and
f'(3).
b. Observe that the work to find f'(a) is the same, regardless of the value of a.
Based on your work in (a), what do you conjecture is the value of f'(4)? How
about f'(5)? (Note: you should not use the limit definition of the derivative to
find either value.)
c. Conjecture a formula for f'(a) that depends only on the value a. That is, in the
