find all points where the function is discontinuous.\na. x = - 2, x = 6\nb. x = - 2\nc. none\nd. x = 6

Explanation:

Step1: Recall continuity criteria

A function is discontinuous at a point if there is a break, jump, or hole in the graph at that point.

Step2: Analyze the graph

From the graph, we can see breaks at (x = - 2) and (x=6). At (x=-2), there is a jump - like behavior and at (x = 6) there is a hole in the graph.

Answer:

A. (x=-2,x = 6)
