Question

Which of the following describes the graph shown?

Answer 1

third from top down

Explanation:

We can think of f(x) as y

y = 3 if x ≥ 3, y coordinate is always 3, while x coordinate starts at 3 inclusive and goes on toward +∞

y = -1 if x ≤ -1, y coordinate is always -1, while x coordinate starts at -1 inclusive and goes on toward - ∞
