Given the following functions: (20 marks each) 1. y = x-4 22 1 2. y2-1 For each function, sketch the curve and determine (where applicable): a. x and -intercepts b. Sign chart c. Horizontal, vertical, and slant asymptotes d. End behaviour e. Critical points f. Slope chart g. Points of inflection h. Concavity chart Sketch the functions on graph paper with properly labeled axes and make sure to label the coordinates or equation of all important features, including the intercepts, asymptotes, critical points, and points of inflection.
