Determine The Inverse G(X) Of The Function F(X) = (1+(4/X)), Stating Its Domain And Range. Verify That F(G(X)) = G(F(X))=X And That G′(F(X)) = (1/(F′(X))

Calculus > inverse function

[fiction-factory]

Hi. Read this and have a go at finding the inverse by following the same steps and I'll then comment on your effort

[fiction-factory]

I will start you off.
g(x)= 4/(x-1)
Check this by substituting in different vales then substituting the resultant value into the inverse

[fiction-factory]

^ ...which should get you back to the initial values

Any progress, chin?

[chin123456]

how to substituting in different vales then substituting the resultant value into the inverse? You also did not ive a step by step example that is similar to the question that is been asked, how do you expect me to be able to follow with only just a sentence statement?

[TonyV]

What " Only one sentence statement" are you referring to?

[chin123456]

You yourself post this Check this by substituting in different vales then substituting the resultant value into the inverse follow by ^ ...which should get you back to the initial values and reply to me yourself, you dont remember already and the link that you post to me doesnt even help me to do my assignment at all, its useless, as the link only explain the theory part of the question only, it does not have a similar step-by-step working solution example that is similar to the question that I asked early on, I am requesting help here to complete my assignment not requesting help here for Calculus leisure learing purposes and I have a dateline to meet and submit this assignment also, I have already told you before! By reading the link that you post to me it only helps me to understand the theory part of this question topics only, it does not help me to be able to do my math assignment!

[fiction-factory]

No need to be so rude. I am sure you don't expect any further help now. I wish I'd just said 'do your own homework' . I think you are doing the wrong course.

[chin123456]

I am not been rude, is you ask me how is my progess? I am just frankly telling you the truth only. An another thing is that I hope you understand that math is not a just a theory-based question like science or history is a theory based question, if your just explained what is the theory of the specific math topic, without giving a similar step-by-step solution example to guide those who are weak in math, how do you expect them to figure out how do this particular math question. As you only provide me a link that explain what is the theory of this math question, with the example that is not similar to the question that I am asking for help, how do I figure out how to do my math question, if you look carefully, there are 4 parts in this question, the link that you provide only explain 2 parts theory of my math question not all 4 parts theory of my math question.

[fiction-factory]

Well there's no point in me going through step 4 if you don't know how to do step 1. Everything needed for step 1 was in that link. I did say try it and then I'd comment. If you'd managed it I could have moved onto step 2. You have to make a bit of effort in maths and change the numbers or adapt an example slightly. You'll never pass an exam just by copying someone's answers in class.

Just the one math, is it?

[jim360]

Pro tip: Don't be rude to the people trying to help you.

[fiction-factory]

Morning jim. chin even had a go at me for something TonyV asked. My link seemed pretty good and covered everything (including domain and range) apart from the calculus differentiation bit . You can lead a horse to water ...

[jim360]

I didn't look at the link but then I didn't need to in order to know that you'd sent him something useful :)

[THECORBYLOON]

What you are saying is you don't want help, you want the full answers showing each step.

You might not get the help you asked for and you might be frustrated by that but your attitude has not helped.

If nothing else, that should be a lesson learnt.

[ToraToraTora]

go easy, the poor lad only has one math!

[drmorgans]

Does the function resolve to x^2 - x - 4 = 0 ?

[fiction-factory]

I think you have just solved x= 1+(4/X), drmorgans, although I hesitated about responding to you because last time on the optimization problem you were right and my back of a postage stamp solution was wrong.
We never did get any feedback on your excellent solution to the misi-stated optimization problem on car washing/polishing

[Peter Pedant]

hi boys - which one was that?
