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 all real numbers, so the range is (-∞, ∞).

__

The graph shows the focus and directrix as well as the parabola.
