Teacher Xu, Please Take Care of the Reckless Students in Your Class

Thank you for the monthly pass of [Young Master Wushang]!

Thank you for your support!

The sixth update is here, and there will be a seventh update later!

Ask for support! .

7 I am a Chinese language teacher, you are here to ask my students about their mathematics situation? [Ask for flowers and evaluation tickets]

Except for Xu Heng, all the teachers stared at this girl with wide eyes.

"I remember your name is He Xiaohua, right?"

The girl smiled and said, "My name is He Ruohua!"

The teacher was embarrassed.

"Om..."

Zhao Kailongnao melon seeds buzzed.

Wei Minghai said, "Teachers, is it alright now? You have all answered the questions! We have answered them as well."

Zhao Kailong's face was ashen, "She is her! You are you! You are different!"

But He Ruohua said, "I'm the worst mathematician in our class, and I can answer it all. It was everyone who gave me the opportunity. I think other people already have the correct answer in their hearts."

Zhao Kailong, "!!!"

"Impossible! Don't talk nonsense! You, you..."

He felt that He Ruohua was lying.

Xu Heng, "She didn't lie, she is indeed the worst mathematician in our class."

Because in terms of mathematics, He Ruohua's mathematical attribute points are the worst.

Xu Heng noticed that she was very interested in sports and was planning to add her attribute points to sports.

not tall!

Slightly Lolita!

Add sports attribute points?

Lovely...weird loli?Violent loli?

Hiss... It's a little exciting to think about it!

He Ruohua, "Mmmm! Thank you Teacher Xu for proving it for me! Hehe."

She smiled, revealing a pair of small tiger teeth.

Zhao Kailong, "This, this...this..."

Zhao Ruiyun also frowned.

Several math teachers even looked at each other.

"Really? Or fake?"

Zhao Kailong gasped, "It's just multiple-choice and fill-in-the-blank questions! Wei Minghai, come here! I'm going to give you a question!"

"If you can answer it! I apologize to you!"

Wei Minghai, "Not to apologize to us, but to Teacher Xu! You were the one who wasted his time!"

Zhao Kailong, "!!!"

"Didn't you say my question is easy! Good! I'll give you another one!"

He wrote viciously:

已知函数f1（x）=3^|x-p1|，f2（x）=2*3^|x-p2|（x∈r，p1，p2为常数）。

The function f(x) is defined as: for each given real number x,

f(x)=f1(x), f1(x)≤f2(x)

f(x)=f2(x), f1(x)>f2(x)

Find the necessary and sufficient conditions for f(x) = f1(x) to hold for all real numbers x (represented by p1 and p2).

"That's it! If you can do it! I apologize immediately!"

"Half an hour... no, is one hour enough?"

"Here are pens and scratch pads!"

Wei Minghai looked at the question and didn't speak.

Zhao Kailong, "Wei Minghai, you sit down and answer the question seriously! What? Did you think the question would be so difficult?"

Wei Minghai has been silent all the time, and he doesn't use a pen to calculate.

Zhao Kailong is happy!

"Hahaha……"
