Question

Anyone knows the answer?

Answer 1

The x coordinate of the parabola will be halfway between x = 3 and x = 9

That is at x = 6.

Answer 2

Hi there!

The x-coordinate of the vertex is the mean, or average of the x-intercepts of the parabola.

Let's take the mean of 3 and 9, which are the x-intercepts.


`(3+9)/(2)`


`= (12)/(2)`


`=6`

That's your answer.

Have an awesome day! :)
