Answer:
- domain: (-∞, 3]
- range: (-∞, ∞)
Step-by-step explanation:
The focus is to the left of the vertex, so the parabola opens to the left. The domain is all values of x less than or equal to 3: (-∞, 3].
The vertical extent of the graph is <em>all real numbers</em>, so the range is (-∞, ∞).
__
The graph shows the focus and directrix as well as the parabola.
