Answer:
Step-by-step explanation:
The choices appear to have been written incorrectly. They should be
7(3)ⁿ⁻¹
3(7)ⁿ⁻¹
3(7)ⁿ⁺¹
common ratio r = a₂/a₁ = 7
nth term = a₁rⁿ⁻¹ = 3(7)ⁿ⁻¹
Answer: 
2. Vertex: (-5, 4) Focus: (-6, 4) Directrix: x = -4
<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 = (x + 3)² - 6 → a = 1 (h, k) = (-3, -6)
