A formula for the derivative of a function is given. How many critical numbers does have? -0.1|x| 1'(x) = sin(x) - 1 critical numbers [-/1 Points] DETAILS SCALCET9 4.1.041. Find the critical numbers of the function. (Enter your answers as a comma-separated list. If an answer does not exist, enter DNE.) F(x) = x4/5 (x = 6)2 [-/3 Points] DETAILS SCALCET9 4.2.019. Find the number c that satisfies the conclusion of the Mean Value Theorem on the given interval. (If an answer does not exist, enter DNE.) () = x, (0,9) Graph the function, the secant line through the endpoints, and the tangent line at (c, f()). y 8 2 8 3 2 x x 2 4 6 8 1 2 3 2 4 2 Are the secant line and the tangent line parallel?
