The answer is : So What you basically need to do is circle and fill over 0 and 4. The answer would be C. A and B are wrong you need to look out for the signs basically. Hope this helps

Domain of function f(x) is 0 ≤ x ≤ 4.
Now look at the domain of graphs A - D.

A) Domain 0 ≤ x < 4 (empty circle for x=4) so answer A is wrong.
D) The same as A but for x=0 (empty circle) so domain is 0 < x ≤ 4.
B) Here we have 0 ≤ x < 5 so B is also a wrong answer.
C) Correct one (0 ≤ x ≤ 4)
