The polynomial functionwill give the maximum number of interior regions formed in a circle if x points on the circumference are joined by all possible chords. For x = 1, 2, 3, 4, and 5, see FIGURES A–E.

For example, in FIGURE A we have 1 point, and because no chords can be drawn, we have only 1 interior region. In FIGURE B there are 2 points, and 2 interior regions are formed. Apply this information and work Exercises in order.

Use the given polynomial function to verify that ƒ(1) = 1 and ƒ(2) = 2.
