This question has several parts that must be completed sequentially. If you skip a part of the question, you will not receive any points for the skipped part, and you will not be able to come back to the skipped part. Tutorial Exercise Determine the point(s), if any, at which the graph of the function has a horizontal tangent line. y = x2+ 12x Step 1 Recall that the derivative of a function gives a formula for finding the slope of the tangent line at any point on the graph of the function. First, find the derivative of y = x2 + 12x. y' = - [x2 + 12x] x + Submit Skip (you cannot come back) Need Help? Read It
