Question

What does f:R→R mean? or something equivalent to it? How to read it?

Answer 1

Answer:

Set of Values of F(x) obtained by putting all elements of domain is called as range. And Set of values which you can put in F(x) in place of x is its domain. Now coming to your question. R means set of real numbers. It implies domain of function is R and corresponding range is also R.

Answer 2

Step-by-step explanation:

$set \: of \: values \: of \: f(x) \: obtained </p><p></p><p>\: by \: putting \: all \: elements \: of \: </p><p>domain \: is \: called \: as \: range \: and \: set \: of \: the \: values \: which \: you \: can \: put \: in \: f(x) \: in \: the \: place \: of \: x \: is \: d \\ called \: domain. \: here \: r \: means \: a \: set \: of \: the \: real \: numbers \: which \: implies \: that \: domain \: of \: the \: function \: is \: R \: and \: corresponding \: to \: the \: range \: is \: also \: R$
