Explanation:

For each input, we must determine which expression is valid for the value of x. The expressions and their ranges are in the orange boxes at the top of the spreadsheet.

The value of x (orange cells) is then matched with the ranges. The valid expression is marked with "y" and highlighted in yellow.

The identified valid expressions are then solved with the value of x provided (bottom half of table, with green cells).
