Answer 1

I think its D on edge!

Explanation:

Answer 2

Graph having x ≤ 0

Explanation:

f(x) =
`√((-x))`

Given function 'f' when reflected across the y--axis,

Translated form of the parent function will be,

g(x) =
`√((-x))`

Table for the input-output values for this function will be,

x g(x)

-1 1

0 0

1 undefined

4 undefined

Table shows that the given function is undefined for x > 0

Domain of g(x) will be (-∞, 0],

Therefore, graph having values of x ≤ 0 will be the answer.
