Question

What is the domain of this function?

Answer 1

domain is the independent variables or the x.
so i say D {-1,3,5} based on the arrows

Answer 2

Correct option is:

D. {-1,3,5}

Explanation:

We have to find the domain of the function defined in figure.

The domain of f(x)=y is all the possible values of x for which the function is defined

Here, f(-1)=2

f(3)=6

and f(5)=8

Hence, all the possible values of x are:

{-1,3,5}

Hence, Correct option is:

D. {-1,3,5}
