Find the domain and range of a parabola with vertex (3, 4) and focus (1, 4).
1 answer:
9514 1404 393
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.

well, if the diameter is 5, thus its radius must be half that, or 2.5, and therefore, the radius of the one four times as much will be (4)(2.5).
Let's simply get their difference, since that'd be how much more is needed from the smaller to larger sphere.
