Answer:
Step-by-step 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) = [tex]\sqrt{x}[/tex] <=> x ≥ 0
2. n(x) = [tex]\sqrt[3]{2-x}[/tex] <=> x belongs to all real number
3. z(x) = [tex]\sqrt{x-2}[/tex] <=> x-2 ≥ 0 <=> x ≥ 2
4. q(x) = [tex]\sqrt{2-x}[/tex] <=> 2 -x ≥ 0 <=> x ≤ 2
5. h(x) = [tex]\sqrt{2+x}[/tex] <=> 2+x ≥ 0 <=> x ≥ -2
6. v(x) = [tex]\sqrt{-x}[/tex] <=> = -x ≥ 0 <=> x ≤ 0
Hope it will find you well.
