1. Find the linearization L(x) - S(a) + S'(a)(x-a) centered at a = 3 for f(x) = 4x- 2. Use the first derivative test to locate the local extrema of f (x) = x (x -16 ). Make sure to include a sign chart or other justification for your answers. Use the second derivative test to -4. Make sure to include a sign chart or othe
