Answer:
see below (upper left)
Step-by-step explanation:
When the x-values are sequential, a linear function will have y-values that differ by the same amount.
The upper left table has y-values that differ by -2.
The upper right table has y-values that differ by 2, -6, 2. These values are not the same.
The lower left table has y-values that differ by -1, 5, -13. These values are not the same.
The lower right table has y-values that differ by 1, 3, 5. These values are not the same.*
__
The upper left table represents a linear function.
_____
* The <em>2nd</em> differences are a constant 2, so this table represents a <em>2nd</em>-degree polynomial.
Recall your d = rt, distance = rate * time
thus
notice, the first car leaves at "x" time, the other leaves on hour later, or x + 1
the first car travels some distance "d", whatever that is, thus
the second car, picks up the slack, or the difference, they're 380 miles
apart, thus the difference is 380-d
