Hello!
75 + 90 + 79 + q = 360
q = 360 - 244 = 116
Stay safe!
Answer:
(2, -4).
Step-by-step explanation:
x^2 - 4x
= (x - 2)^2 - 4.
So the vertex is at
(2, -4).
Answer:
1, 7, 34, 7, 1
Step-by-step explanation:
Plug in the answer choices:
A.
1, 7, 34, 7, 1
B
1, 10, 28, 10, 1
C
2, 8, 30, 8, 2
D
2, 4, 38, 4, 2
E
5, 5, 30, 5, 5
20
Explanation:
20 + 4 = 24. Therefore 24-20=4
For the function: y = x² + 4
For the function: x² - 4
- x intercept: (-2, 0) and (2, 0)
For the function: 1 - x²
- x intercept: (1, 0) and (-1, 0)
Conclusion:
green line = x² + 4; blue line = x² - 4; black line = 1 -x²
