There is a picture of a function's graph with a curve CONNECTING the following points on the xy-plane:

(-6, 3), (-3, 0), (0, 3), (2, 4), (6, 0), (8, -2), (10, 0)

and (11, 1).

QUESTIONS: a - d.

(a) Is f(8) positive or negative? Why? Why not?

(b) For what numbers x is f(x) > 0?

(c) What are the x-and y-intercepts, IF ANY?

(d) How often does the line y = 1/2 intersect the graph?

Thanks!
