Answer: Fourth option.
Step-by-step explanation:
By definition, a relationship is a function if and only if each input value (or each x-value) has only one output value (or y-value).
Given the first table:

You can notice that the input values 2 and 3 do not have only one output value. Therefore, this table does not represent a function.
The second table is:

You can notice that the input values 4 and -4 do not have only one output value. Therefore, this table does not represent a function.
The third table is:

You can notice that the input values 6 and 7 do not have only one output value. Therefore, this table does not represent a function.
The fourth table is:

You can notice that each input value has only one output value. Therefore, this table represents a function.

Answer:
Total earned= $273
Step-by-step explanation:
Giving the following information:
Regular labor hours= $5.25
Overtime labor hours= $5.25*1.5= $7.875
<u>To calculate the total earned, we need to use the following formula:</u>
Regular labor hours= 40*5.25= 210
Overtime labor hours= 8*7.875= 63
Total earned= 210 + 63
Total earned= $273
