Show all work on every question where appropriate. 1. Given f (x) =4x -5x + 7 , use the limit process to find the formula for the derivative. 2. Given g(x) = Vx-3, use the limit process to find the formula for the derivative. 3. Given f(x) =x -7x+6, use the alternate form of the limit process to find the slope of f (x) at (2, -4)
