Find the domain and range of a parabola with vertex (3, 4) and focus (1, 4).

9514 1404 393

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.
