Question

Domain of the function

Answer 1

@ganeshie8 @mathmale please help with this

Answer 2

All the 'x' values of a graph form the Domain set.
See which values of x which give a function value.

This is what I mean.

Answer 3

Looking at y our illustration (picture.png): do you see any restrictions on the (input) x-values? Is the graph broken (discontinuous) for any particular x-value? If not, what's your conclusion about the domain of this function?

Hint: one possible definition of "domain" is "the set of all acceptable input values of the given function."
