Alevel doubt

xto the power of 2divided by3 then multiplied by x+2 in the bracket .
2nd question isx under root = 1 divided by x under root for x more than 0 please if you can pm same question in paints format so i will tell you iff the question is correct or not as it would difficult for you to understant in this way thanks

What are we suppose to do in these questions?

 

[1357913579]

soory forgot to write for each of the foolowing functions f(x) find f inverse of x the interval at which f(x) is decreasing and the interval at which f(x) is increasing

 

[destined007]

are these the questions?

 

[1357913579]

no for questin number one its first x to the power of the power is 2 divided by 3 then this x is multiplied with x + 2 which is in the bracket. and question 2 is x inside the root + by 1 which is divided by x under root

 

[destined007]

refer to the above image and tell me.

 

[1357913579]

first is ok but question number 2 is x under root sepapately it is added to 1 divided by anather x

 

[destined007]

If 1st question is right then i can't find the inverse of this function because i have never ever done this type of question before. Are you sure its inverse? aren't we suppose to find derivative?

 

[1357913579]

this is question no. 2

 

[1357913579]

in question number one its written f and there is a dash up and x in the bracket.

 

[destined007]

Oh man. If there is a dash, it means derivative. For inverse functions there will be "-1" written.

 

[1357913579]

its like this in picture
and for question 2 as isaid previosly its for x is more than 0

 

[Nibz]

^ It's a derivative.
