Please answer the following

Consider the curve ry = 5. . Solve for y and find dy da explicitly. . Find- dy dx - using implicit differentiation. . Explain using another example the difference between implicit and explicit differentia- tion. (2) Draw the curve given by the equation x2 + y = 9. Does this graph represent a function? Explain. Find equations of the tangent and the normal to this circle at the point (2, V5). Draw the tangent and normal in the diagram above
