Chapter 108 Difficulties
Song Ranran didn't stay in the living room on the first floor for too long. After resting on the sofa for a while, she also went back to her room upstairs.

Although it is the weekend, the study time should not be too relaxed.

After all, there is still so much review content waiting.

After returning to the room, Song Ranran went to the desk next to the wall, and then sat on the chair inside.

She first took out the homework assigned by the school this weekend from her schoolbag, and after finishing it, she took out a purple-covered five-year college entrance examination and three-year simulation and began to study the questions daily.

Once you start to do the immersive questions, time seems to be pressed a shortcut key, and the time goes by very fast.

When Song Ranran looked up again, it was already three hours later.

At noon, she went down to have lunch and brought a plate of fruit after dinner.

After taking a nap for an hour, Song Ranran got up to wash her face with cold water, and continued to study in the afternoon.

After an hour and a half.

The pen in Song Ranran's hand stopped at one place, and her lowered eyes fell on a big math problem on the opened page.

His brows were slightly raised, as if he had encountered some difficulty.

The question she is currently working on is a math function question, and it is also the final question of a certain test paper. The difficulty can be regarded as five stars.

Let the function f(x)=loga(x-3a) (a is greater than 0 and a≠1), when the point P(x, y) is a point on the image of the function y=f(x), the point Q(x- 2a, -y) is a point on the graph of the function y=g(x).

There are three questions in this question, and the difficulty increases in order.

The first small question is just to find the analytical formula of y=g(x), and the second question is to find the value range of a under certain hypothetical circumstances.

It didn't take much time for Song Ranran to follow the routines of the previous two questions.

But when she saw the third question, Song Ranran tried to do the math. She wrote a lot of numbers and letters on the white draft paper, but she stopped when she reached a certain part.

The third question is to first translate the image of g(x) to obtain a new function, and then assume a new function, given that the maximum value in a certain interval is five quarters, it is necessary to determine the value of a .

Song Ranran: "..."

Looking at the short two-line description, Song Ranran tried to draw a rough image based on the topic to see what it looked like.

It's just because the image of the previous question has changed a lot, Song Ranran felt a little messy while drawing.

Rubbing between her brows, she decided to do the math first...

Well--

No solution.

Song Ranran: "..."

After three seconds of silence, she opened the answer analysis attached at the end. After finding the location, she looked at the question and the analysis.

A few minutes later, Song Ranran stopped, her brows still frowning slightly.

The analysis of this answer is not particularly long, the final answer number is indeed clearly written, but... what about the process?

There is an important part of the reasoning process in the middle, and I don't know if it is a printing problem or a writing problem, which has been omitted.

After reading it roughly, Song Ranran could understand [-]% to [-]% of it, but she stared at the math problem, her curiosity was aroused, and she wanted to know what the whole process should be like.

With slightly raised eyebrows, Song Ranran thought for a while, and a thought flashed through her mind.

Doesn't the family happen to have a ready-made master student...

Rong Zhou should definitely know this question...

Why don't you ask him?
Thinking in her heart, Song Ranran got up and took books, notebooks and pens, opened the door and walked up the stairs to the third floor.

 Thanks to the orange-flavored cat lady for voting for the two monthly tickets!Thanks for the support from Little Fairy Su Yi and Little Fairy Lazy Cat under the air conditioner!Comparing my heart, (づ ̄3 ̄)づ╭~

  The math problems involved in this chapter were found by me on a big problem on a certain paper. No need to learn math hehe.
