2. The graph below shows the curve defined by the equation x = y5 - 5y3 + 4y. a. The point (0, 1) is on the curve. Sketch the tangent line at this point and estimate its slope. b. Use implicit differentiation to find the exact value of slope of the tangent line at (0, 1). Show all your work! The exact slope that you find should be close to your estimate
