Cho hai đường thẳng x x' và y y' cắt nhau tại O. Gọi tia Ot và O' lần lượt laftia phân giác của xÔy và x'Ôy'. Chứng tỏ tia Ot và tia Ot' là 2 tia đối nhau.

d

step-by-step explanation:

by observation, we can see that the the graph is simply the graph of y = |x| that has been shifted 4 units downwards and 3 units to the left.

we can recognize in choice d :

y = | x + 3 |   - 4 (rewriting in general form)

y = | x - (- 3) |   - 4

the "-4 " term means   that the graph has been shifted by 4 units in the negative y direction

the "-3 " term means   that the graph has been shifted by 3 units in the negative x direction

this matches our observation of the graph described above.
