et y be defined implicitly by the equation ln(7y)=3xy. Use implicit differentiation to find the first derivative of y with respect to x. dx dy ​ = Use implicit differentiation to find the second derivative of y with respect to x. dx 2 d 2 y ​ = Note: Your answer should only involve the variables x and y. You should simplify your answer as much as possible before entering it into WeBWorK. Find the point on the curve where dx 2 d 2 y ​ =0. dx 2 d 2 y ​ =0 at the point (x,y)=()
