Please help me answer A-D

Conside following polynomial function. f (x) = (x+ 1) (x-1) Answer the questions regarding the graph of f. Then, use this information to graph the function. (a) Choose the end behavior of the graph of f. 0.0,... None Choose One X (b) List each real zero of f according to the behavior of the graph at the X-axis near that zero. If there is more than one answer, separate them with commas. If there is no answer, click on "None". Zero(s) where the graph crosses the X-axis: Zero(s) where the graph touches, but does not cross the X-axis: (c) Find the y-intercept of the graph of f: (d) Graph f (x) - (x+ 1) (x- 1) by doing the following. . Plot all points where the graph of f intersects the X-axis or y-axis. . For each point on the X-axis, select the correct behavior. . Click on the graph icon. check
