Answer:
<h2>On a coordinate plane, a parabola opens up with x-intercepts at (negative 2, 0) and (2, 0), and a y-intercept at the vertex (0, negative 4).</h2>
Step-by-step explanation:
Parabollas are characterized by being curves which opens upside or downside.
When the parabolla opens upside, then we say it has a minium.
When the parabolla opens downside, then we say it has a maximum.
In either the minium or maximum point is defined by the vertex.
As you can observe, among the choices, the last one is the only one that opens up, therefore, it has a minimum value vertex.

I'm kinda confused the question is weird to me so I don't know if this is right
Answer:
Option E) is correct
If n is an odd number then 2(n+1) represents an even number.
Step-by-step explanation:
Let X=set of all odd numbers
that is ![X={\{1,3,5,7...}\}](https://tex.z-dn.net/?f=X%3D%7B%5C%7B1%2C3%2C5%2C7...%7D%5C%7D)
Let Y=set of all even numbers
that is ![Y={\{2,4,6,8...}\}](https://tex.z-dn.net/?f=Y%3D%7B%5C%7B2%2C4%2C6%2C8...%7D%5C%7D)
Verify that 2(n+1) represents an even number where n is an odd number:
Put n=1 in 2(n+1) we get
2(1+1)=2(2)=4
Put n=3 in 2(n+1) we get
2(3+1)=2(4)=8
Put n=5 in 2(n+1) we get
2(5+1)=2(6)=12
and so on.
From above results we get 2(n+1) represents an even number and is belongs to the set Y when n is an odd number.
Therefore Option E) is correct
If n is an odd number then 2(n+1) represents an even number.
