\f(1 point) Let y be defined implicitly by the equation 1n(7y) = 3xy. Use implicit differentiation to find the first derivative of y with respect to x. Q_ dx Use implicit differentiation to find the second derivative of y with respect to x. : dx2 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. . . dzy Find the pomt on the curve where d2 = 0. x 2 = 0 at the point (x, y) =( )' dx2
