Let f(x) = x² + 2x. (a) Find the derivative f' of f. f'(x) = 2x+2 Nicely done! (b) Find the point on the graph of f where the tangent line to the curve is horizontal. (Hint: Find the value of x for which f'(x) = 0.) (x, y) = -1,-1 (c) Sketch the graph of f and the tangent line to the curve at the point found in part (b).
