青チャート数学I+Aの78番、二次関数の対称移動の問題です。 放物線をX軸方向に－I、y軸方向に8だけ平行移動すると書いてあるのに、どうして+I、－8をしているのでしょうか…？ 解答お願いします🙏

After breakfast, my host father suggested that one of 10 these days he would invite me to a Viking dinner. I didn't understand Viking, but I'm curious. So far, I have learned lots of these words. My teacher calls them wasei-eigo. These words can be deceptive; they look like real English, and yet they are not. I find them 15 confusing. However, confusion is not a bad thing. It's a first G-2 step in learning something new. Finally, my advice to you: Don't be surprised if native speakers look puzzled when you use wasei-eigo.

They found that some samples contained much higher populations of microbes than expected. この分に使われてるthatって何の役割で置かれてるんですか
