Curve Sketching part 1 Steps Original function #1 Find the x and y intercepts Find any red flags in the domain and state if they create any vertical asymptotes Find the end behavior to the function. Find the first derivative Find the critical points using the first derivative Find the intervals of increasing and decreasing using the first derivative State ordered pairs for all minimums and maximums by using the intervals of increasing/decreasing and the original function Find the second derivative Find the inflection points using the second derivative Find the intervals of concavity using the second derivative State the ordered pairs of the points where concavity changes occur using the intervals of concavity and the original function Graph in the following order: - intercepts - vertical asymptotes - min’s and max’s - inflection points - now connect the dots keeping concavity and end behavior in mind.
