Answer:
y = -(x - 2)² - 4
Step-by-step explanation:
- The vertex of this function is (2, -4), which is given in the table
The vertex form an equation is given as :
- y = a(x - h)² + k
- Substitute the vertex
- y = a(x - 2)² - 4
Substitute any point in the table to find a :
- -8 = a(0 - 2)² - 4
- 4a = -4
- a = -1
Hence, the final equation :
- y = -(x - 2)² - 4
- Option 2
