Use the four-step process to find the slope of the tangent line to the graph of the given function at any point. (Simplify your answers completely.) f(x) = -x^2 + 4x Step 1: f(x + h) = -(x^2 + h^2 + 2hx) + 4 + 4h Step 2: f(x + h) - f(x) = -h(h + 2x) - 4 Step 3: (f(x + h) - f(x)) / h = -(h + 2x - 4) Step 4: f'(x) = lim h->0 (f(x + h) - f(x)) / h = -2x + 4
