Answer:

Step-by-step explanation:
x-intercepts are when the curve intercepts the x-axis, so when y =0.
Therefore, to find the x-intercepts, substitute y = 0 and solve for x.
The vertex is the turning point: the minimum point of a parabola that opens upward, and the maximum point of the parabola that opens downward. As a parabola is symmetrical, the x-coordinate of the vertex is the midpoint of the x-intercepts.
Equation: 



Therefore, the x-intercepts are x = 0 and x = 2
The midpoint of the x-intercepts is x = 1, so the x-coordinate of the vertex is x = 1
Equation: 



Therefore, the x-intercepts are x = -5 and x = 4
The midpoint of the x-intercepts is x = -0.5, so the x-coordinate of the vertex is x = -0.5
Equation: 



Therefore, the x-intercepts are x = 0 and x = 3
The midpoint of the x-intercepts is x = 1.5, so the x-coordinate of the vertex is x = 1.5

Answer:
2. 3-(-2)-(+5)
⇒3-(-2)-(+5)= 3+2-(+5) = 5-(+5) = 5-5 = <u>0</u>
3. -(-3-6)-(-4+8)
⇒ -(-9)-(-4+8) = 9-(-4+8) = 9-4 =5
4. -8-(-3-2)
⇒ -8-5=-13
5. -(-(-5))+7
⇒ -5+7 = 2
6. -(-(-8)+3)
⇒ -(11) = -11
7. -(-6-(-3+1))
⇒6-(-3+1) = 8
8. 1-(14-(11-7))
⇒ 1-(14-4) = 1-10 = -9
There are 4 cups in one quart, so if you do 2 1/2 times 4 you will get 10. That means the pitcher holds 10 cups.
