1. Use the limit definition of the derivative to compute the derivative of f(x) = x2 + 2x - 3. 6 2. Find the equation of the tangent line to the graph of the function f(x) = at the x+2 point (0, 3). (Use the limit definition to find the slope at x = 0.) 3. a) Sketch a graph of a function whose derivative is always negative. b) Sketch a graph that is differentiable everywhere, except at x = 4. c) The function h(x) is graphed in the figure below. Sketch a graph of its derivative, h' (x). 0.5 31 5 -01.5
