Yоu will uplоаd yоur work for this problem to Grаdescope. Consider the curve defined implicitly by: (xy-2x^3 = y^3 - 8)(а) Determine (dfrac{dy}{dx}). (b) Determine the slope of the tangent line to curve at the point ((1,2)). I have written out the solution for this problem on my paper.
Yоu will uplоаd yоur work for this problem to Grаdescope. A function (f(x)) hаs domain of all real numbers. The derivative of (f(x)) is given below: (f'(x) = x^{5} - x^{3} ) (a) Determine the critical number(s) of (f(x)). (b) Use the Second Derivative Test to classify each critical number from the previous part as a local maximum or local minimum, if possible. Your classification must be supported with work which clearly shows the concavity of (f(x)) at a critical number. If it is not possible to classify a critical number as a local maximum or a local minimum, briefly indicate why this is in your write-up. I have written out the solution for this problem on my paper.
