Question

Cn Part A - Knowledge/Understanding and Application, Making Connections Sketch the rational function f (by first analyzing its key features/properties by x32x2-11x-12 hand: domain, intercepts, asymptotes, and behavior near the asymptotes. You would notice that there is one optimum value needed before we can sketch the curve. 2) Is it possible for us to calculate the optimum value first before sketching the curve? State your prediction and justify your reasons for saying yes or no. You may choose to show calculations or just explain clearly with words. Now, type the function onto DESMOS and check the optimum value. What is the optimum value? Is it a maximum or minimum? Was your prediction correct? Justify why you were correct or not.
