Find the domain of the graph function.

The domain is the set of feasible inputs, i.e. the x-coordinates in which you can evaluate the function.
We can see that this function is defined only for x values between -1 and 3 (included), so this is your domain.
Answer:
C. [tex]-1\leq x\leq 3[/tex].
Step-by-step explanation:
We have been given graph of a function. We are asked to find the domain of our given function.
We know that domain of a function is all values of x for which our given function is defined.
We can see that our given function is defined for values of x that are greater than or equal to [tex]-1[/tex] and less than or equal to 3.
Therefore, the domain of our given function would be [tex]-1\leq x\leq 3[/tex] and option C is the correct choice.
