Answer:
Explanation:
To have all the function are defined, all the values in the square root must be ≥ 0 and the value in the cubic can be all real number
1. s(x) =
<=> x ≥ 0
2. n(x) =
<=> x belongs to all real number
3. z(x) =
<=> x-2 ≥ 0 <=> x ≥ 2
4. q(x) =
<=> 2 -x ≥ 0 <=> x ≤ 2
5. h(x) =
<=> 2+x ≥ 0 <=> x ≥ -2
6. v(x) =
<=> = -x ≥ 0 <=> x ≤ 0
Hope it will find you well.
