Question

CAN SOMEONE PLEASE ANSWER!

Answer 1

the third statement is correct

The domain of the graph is all real numbers less than or equal to 0

Note that $\sqrt{-1}$ is not real and so the value inside the square root must be positive or 0

f(- 1 ) = $\sqrt{1}$ = 1 which is real

f(- 4 ) = $\sqrt{4}$ = 2 which is real

Thus the domain must be values of x less than or equal to zero

Answer 2

The third statement is correct !
