Step-by-step explanation:

Subtract each two consecutive numbers on the left side.

4 - 5 = -1

3 - 4 = -1

2 - 3 = -1

1 - 2 = -1

Now subtract each two consecutive numbers on the right side.

1 - 2 = -1

0 - 1 = -1

1 - 0 = 1

2 - 1 = 1

The differences in consecutive x-values are all equal, but the differences in the corresponding y-values are not, so this relation is not linear.

Now we look at the differences of the differences of the y-values.

-1 - (1) = -1 + 1 = 0

1 - (-1) = 1 + 1 = 2

1 - 1 = 0

For equal differences in consecutive x-values, the differences of the differences of the y-values are not equal. That means this is not a quadratic equation.

The relation is non-linear and non-quadratic, but we cannot determine what it is by the finite differences method.
