Question

If (7, 11) and (3, 11) are two points on a parabola, what is the x-value of the vertex of this parabola?

​

Answer 1

5

Explanation:

According to properties of parabola : the vertex

A =
`(a+b)/(2)`

(7,11) , (3,11)

∴ X =
`(7+3)/(2) =(10)/(2) =5`

Answer 2

The answer is 5.

Explanation:

The equation for this problem is

X^1 + x^2/2

Insert the numbers in that equation

7 + 3/2

Do the problem:

10/2

10/2 = 5

Therefore, the answer is 5.
