So let’s say you have (2,8) and (4,12)
Your x values are your first ones. So 2 and 4.
that formula is to find the midpoint so let 2 by x1 and 4 be x2. Add those together you get 6. Then divide by 2. Always by 2. You get 3. That’s the midpoint of those two points. Same thing for the y values.
Answer:
263
Step-by-step explanation:

As we can see
![\\ \sf\longmapsto D_f=\[1,11\]](https://tex.z-dn.net/?f=%5C%5C%20%5Csf%5Clongmapsto%20D_f%3D%5C%5B1%2C11%5C%5D)
So having 1 and 11 as domain we can say the equation is

As it's greater than and equal to the answer can be equal to (=) form.
