3. Curve Sketching Before we can start curve sketching, it is beneficial to find several values: Domain –Always find the domain of f(x) first, so you know where we need to be sketching and where we don’t Vertical Asymptotes –For any point not in the domain of f(x), check the limit approaching that point to see if there is a vertical asymptote

4. First Derivative Info –Determine where f(x) is increasing and decreasing –Find any local extrema (x,y coordinates) Vertical Tangent Lines –At any undefined point in f’(x) and in the domain of f(x), check the limit approaching that value to see if there is a vertical tangent

5. Second Derivative Info –Determine where the graph is concave up and concave down –Locate any inflection points (x,y) coordinates Horizontal Asymptotes –Check the limit of f(x) as x approaches +/- infinity
