What order will result in a final output of 2 when the first input is 8? (See screenshot)

The order that will result in a final output of 2 when the first input is 8 is as follows;

Third → Second → Fourth → First

Step-by-step explanation:

First gives;

y = -2·x + 34 = 18

Second gives;

y = -x/3 - 10 = -38/3

Third gives;

= -24

Fourth gives;

y = (x - 2)² = 36

We have after several iterations;

Third gives;

= -24

Next we input into the second to get;

y = -(-24)/3 - 10 = 24/3 - 10 = 8 - 10 = -2

Next we input into the fourth to get;

y = ((-2) - 2)² =  (-4)² = 16

Next we input into the first to get;

y = -2×16 + 34 = -32 + 34 = 2

Which gives the order as follows;

Third → Second → Fourth → First
