A dog groomer charges her clients by the weight of the dog. The following piecewise function represents the total charge, f(x), for a dog weighing x pounds
2.5x if 0 ≤ x ≤ 20
J（工）三
3.5x if 20 < x ≤ 50
5x ifx > 50
What would be the last point graphed on the first piece of the function, f(x) = 2.5x?

The last point is at x = 20 (included). f(20) = 2.5·20 = 50, so the endpoint is (20, 50) — a closed (filled) dot.
