Homework #4 Problem 1 (5 points): I Compute the first three derivatives of f (x) and then state the formula for the ni derivative of f (x) , if f (x) =_ X Problem 2 (5 points): There are two points on the graph of the equation y =2x' +9x -60x+12 where the tangent line is parallel to the x-axis. Find the x- coordinates of those points. (Hint: When a line is parallel to the x-axis, what is its slope?)
