Use a graphing calculator to find the equation(s) of the tangent line(s) at the point(s) on the graph of the equation y3 -xy-x5 = 12, where x = 2. Give the equation of the line that is tangent to the curve at x=2. y= (Type your answer in slope-intercept form. Use integers or decimals for any numbers in the expression. Round to two decimal places as needed. Round all intermediate values to two decimal places as needed.)
