Unformatted text preview: concave up/down. What are the points of inﬂection? Separate a number line into the intervals on which h ( x ) is: • both increasing AND concave up • both increasing AND concave down • both decreasing AND concave up • both decreasing AND concave down and draw the basic shape of the curve on each interval. (There are four possibilities: each would be the left or right half of the shapes ∪ and ∩ .) Now piece your shapes together to draw the function h ( x ) below. Label all intercepts, local extrema, inﬂection points, removable discontinuities, and asymptotes....
