6. Definition of Derivative - Homework For the following functions, find their derivatives and evaluate at x = 2, -4, 0, and it. Use proper notation. 1. y = 2x 2. f (x ) = x2 - 5 3. f(x) =x2+3x-4 4. f(x) = 6x-4x2 5 . 8 ( x ) = 1 +2x X. h (x ) = =+1 7. An alternative method for finding f'(a) is to use the formula f'(a) = lim (). Use the formula to x - a find f' (5) for f (x) = 3x2 - 8x-10. O www.
