Answer:
<u>Step-by-step explanation:</u>
The vertex form of a parabola is y = a(x - h)² + k or x = a(y - k)² + h
- (h, k) is the vertex
- p is the distance from the vertex to the focus
- -p is the distance from the vertex to the directrix
1) y = -2(x - 4)² - 1 → a = -2 (h, k) = (4, -1)
*******************************************************************************************
2) x = (y - 1)² + 2 → a = 1 (h, k) = (2, 1)
