For the function: y = x² + 4
- y intercept: (0, 4)
- x intercept: None
- vertex: (0, 4)
For the function: x² - 4
- y intercept: (0, -4)
- x intercept: (-2, 0) and (2, 0)
- vertex: (0, -4)
For the function: 1 - x²
- y intercept: 1
- x intercept: (1, 0) and (-1, 0)
- vertex: (0, 1)
Conclusion:
green line = x² + 4; blue line = x² - 4; black line = 1 -x²
