Find the equation for a parabola that has a vertex at (0, 4) and passes through the point (–1, 6).
1 answer:
Answer:

Step-by-step explanation:
The vertex form of a parabola:

(h, k) - vertex
We have the vertex at (0, 4) → h = 0 and k = 4.
Substitute:

The point (-1, 6) is on the parabola. Put the coordinates of the point to the equation:
<em>subtract 4 from both sides</em>
