Question : 1.How to solve this question (steps) 2.How to analyse this question

 

Please help me it is emergency, I don't know how to analyse this problem.

Do you know the definition of the domain and range of a function, and do you know how to graph a function?

Should I find out f'(x) and then find the max. or min, value by f'(x)=0

The problems says f(0) is insolvable. How do you manage that?

No Point of intersection the curve of the equation does not touch the y axis

Is it right? and the domain and range mean I need to consider lim?

Limits or asymptotes?

Actually finding the domain of a function is pretty easy. You don't have to calculate the derivative of the functions just only smart moves.

First logarithmic function only works for positive values except the domain is complex numbers. So this is more than enough for your question.

Could you explain it in detail because I am a beginner, thanks

Could you tell us how you do it so far so that we could know where to begin.

How could you possibly be asking how to find the first and second derivatives if you are such a "beginner" that you do not know what "domain" means?

I think you should focus on the bigger picture.

 

You are asked to sketch the curve.

It is therefore reasonable to assume that you have been taught some methods and procedures for doing this.

 

You should tell us what you have achieved in this respect.

 

Definition and use of the term 'domain' are not introduced until university in some countries, although the idea is very simple.

 

The domain is that part of the x axis where the equation makes can be evaluated to provide a y value.

 

So follow your procedures for curve sketching and it will lead you to the rest of the answer for the first part.
