30 / 30 67% + H 4 ) Graph a non-linear function ( where ( '(c) = 0, but there is no local max/min at c. I pt 5) Find the intervals of increase and decrease for ((x) - 4x using critical numbers and test points. 4 pts 6) Find the critical points (x y) of the following function. Then use the Second Derivative Test to 6 pts determine whether they correspond to local maxima or minima or neither: ((x)= x+3x+1 7 ) Graph three examples of critical points (c. f(c)) where f '(c) is undefined. 3 pts
