Question 2 (1 point) When matching the graph of a function f to the graph of its derivative f, some key things to look at are: (select all that are appropriate) C] where the function f cross the x-axis, the derivative f, should also cross the x- axis C] where the function f is decreasing, the derivative fa should be below the x- axis C] where the function f is increasing, the derivative f, should be above the x-axis C] where the function f has a horizontal tangent line the derivative f, should cross the x-axis C] where the function f is below the x-axis, the derivative fa should also be below the x-axis
