Vertex is the point where the graph of the function meets the x function.
This means that we know one of the coordinates of the vertex X=0 always.
We should calculate f(0) in order to find out point Y.
(0-10)^2=(-10)^2=100

Equation:
x/3 = x/8 + 2/3
---
Multiply thru by 24 to get:
8x = 3x + 16
5x = 16
x = 3 1/5
========
<span>(x, y)→(x − 8, y − 7) is the correct translation. Take point D for example. The coordinate of D is (2, 5). The coordinate of D' (after translation) is (-6, -2). Since 2-8=-6, 5-7=-2, only the first choice is correct. You can also try other points and see why only this is the right translation.</span>
