Answer:

-11

Step-by-step explanation:

So, using the fact that one x intercept is 7, and the vertex is (-2,-4), we can solve for the other x intercept. While there are many ways to solve this, the way I prefer to do it is to realize that the x intercepts are the same distance away from the vertex. this means that if the vertex is at x = -2, and one x intercept is at x = 7, the other will be at -11, as 7+2 = -2+11.

Can someone help me please

Wow ! If I understand what's go0ing on here, then
we have to be careful, and THINK .

I was going to ask you "What does Ф mean ?", and then I realized,
Ф is a new operation that the teacher invented.

The first line on the board is the definition of Ф .

Ф means "Add the two numbers and subtract 4."

Now you have to use this new invention to find the value
of the second line:

Take care of the stuff inside the parentheses first: ( 4 Ф 2 )
Add the two numbers and subtract 4
4 + 2 - 4 = 2
That's the part inside the parentheses. It's 2 .

NOW, we have to do the new operation with the 2 inside,
and the 3 that's outside the parentheses:

3 Ф 2
Add the two numbers and subtract 4
3 + 2 - 4 = 1

And that's the final value of 3 Ф (4 Ф 2) . It's 1 .

Pretty sneaky.
