PLUS Session (Curve Sketching)Directions: For the next 30 minutes, work together in groups (3-4) on the following problems/questions. Afterwards, each group will present their solutions and answer questions relating to the correct answers. Everyone must work together! GOOD LUCK! Strategies Toward Curve Sketching:Step 1:DomainA.Determine the domain of f; identify endpoints; find any vertical asymptotes.Step 2:Intercepts A.Determine the x- and y-intercepts of the graph.Step 3:Symmetry/PeriodicityA.Determine whether the function is even, odd, or periodic. Step 4:First DerivativeA.Calculate the derivative and find the intervals for which the function is increasing and/or decreasing from the critical points. Step 5:Second DerivativeA.Calculate the second derivative and find the intervals for which the function is concave up and/or concave down from the points of inflection.
