What do you usually do?”

Xu Sheng: "Sleep."

Xu Sheng felt that this might be a bit difficult for Shao Zhan, and added: "If you can't sleep, I have two comics in my desk, it's your turn."

It was really weird to summarize his early self-study life like this. Shao Zhan was silent for a while before saying: "Memorize words and collect homework."

Xu Sheng thought about it: This is not very difficult.

Both of them tacitly did not mention tattoos or keys.

Strictly speaking, this is considered personal privacy. Now the two are in a special situation. Besides, their relationship is not as familiar as this.

After breakfast, the people in Class 7 of Grade 2 have almost arrived.

After Xu Sheng entered the class, he turned around for a long time before he found the college entrance examination English vocabulary manual. He casually opened a page and looked at it with his chin on his back.

Shao Zhan’s deskmate is a male classmate wearing glasses. Xu Sheng doesn’t have a deep impression of this person, but after all, he only goes through the aisle and knows that he is a serious student in his daily life and belongs to the type of studying hard.

Before Xu Sheng's vocabulary manual was turned over a few pages, his deskmate carefully poked him with a pen.

Xu Sheng turned his head: "Is there anything wrong?"

My deskmate's love for the God of Learning is like a surging river. He is introverted, looks a little shy, and is a little embarrassed to speak. Seeing that he blushed, Xu Sheng looked like he mustered up a great courage to take out a book "High School Mathematics Strengthening Practice Questions" from behind: "The God of Learning has a function question. I read the answer but still don't understand it very much."

As my deskmate said, he opened the green-skinned book that made Xu Sheng tremble for a moment.

It is known that the function f(x)=|x-a|,g(x)=x^22ax1(a is a normal number), and the intercepts of the image of the function f(x) and g(x) on the y-axis are equal.

(1) Find the value of a

(2) Find the monotonic incremental interval of function f(x)g(x)

(3) If n is a positive integer, prove that: 10^f(n)(45)^g(n)＜4

Xu Sheng knew these words separately.

I can't understand even if I put together a single sentence.

He even wanted to ask his deskmate Shao Zhan: What is the intercept?

I also want to ask Shao Zhan himself why he didn't give a question to his deskmate in the morning self-study activity. He doesn't know how to say this question.
