Question

what is the correct notation for a function that has any given imput equal to its output value?

Answer 1

What do you think it is?

Answer 2

If you put a number into f, you get the same number. Take that number as x.

Answer 3

@ParthKohli, you're misunderstanding the question. "any given imput equal to its output value" "any given imput"

Answer 4

imput? huh? LOL

Answer 5

@ParthKohli, it's accepted in the US manual of English style to not modify a person's spelling in quotation of the person. If you do modify it, you have to put the [sic] with italicization. Since you cannot italicize on here, I did not modify the spelling.

Answer 6

the options are
f(x)=f(x)
f(x)=x
f(x)=-x
f(x)=1
and im not sure i understand the question

Answer 7

@eric.fuqua, the idea is this: Given any value \(x\), the function \(f\) takes this value to one value.

Answer 8

Do you understand that language or should I rephrase the question?

Answer 9

i understand now, thank you

Answer 10

f(x) = x

Answer 11

f(x) = x \[\forall x \in R\]

Answer 12

@eric.fuqua, I am not entirely sure @AIW is correct. (Disregarding that you should not post answers. Read the Code of Conduct, AIW.)

My issue here is the use of the possessive pronoun "its". It isn't clear what this pronoun is replacing and it's confusing because there are two possible things which it could replace--which modifies the answer entirely.

Answer 13

Could you possibly ask the person who gave you this work? This phrasing is terribly ambiguous as it stands; I would argue that point if the teacher/professor thinks you should not be asking about this.
