Answer:
This is true. It does. 4.4721, to be exact.
To find the value of x² + (2y) ÷(2w) +3z , first we substitute the values of w, x, y and z
5² + 2(8) ÷ 2(2) + 3(3)
To simplify this further, we have to apply the rule of BODMAS
(Applying the rule of BODMAS simply means when you have an equation, if its having bracket, you have to remove the bracket first, then you move to powers then you proceed to dividing then subtraction and then addition)
5² + 2(8) ÷ 2(2) + 3(3)
=25 +16 ÷ 4 +9
=25 + 4 +9
=38
Therefore the value of x² + (2y) ÷(2w) +3z is 38

========================================
Explanation:
If x repeats itself, then we don't have a function. For instance, relation 2 has the x value -4 show up twice. That input leads to multiple outputs which is why we don't have a function. Relation 4 is a similar story (this time the input 'u' shows up twice).
Relations 1 and 3 don't have this issue, so they are functions.
The array is times between 4 in 2 = 8
