Question

What route can be used to describe the relationship between X and the Y in this table

Answer 1

In order to find which of the given rules is valid to describe this relation, let's check each of them.

Step 1

If we apply the first rule to x = 0, we obtain:

`y=0\cdot2+1=0+1=1\\e3`

Thus, the first rule is incorrect.

Step 2

Applying the second rule for x = 0, we obtain:

`y=0\cdot3-2=0-2=-2\\e3`

Thus, the second rule is incorrect.

Step 3

Applying the third rule to x = 0, we obtain:

`y=0\cdot3+2=0+2=2\\e3`

Thus, the third rule is incorrect.

Step 4

Since this rule is the only one left, let's check it for all the values of x:
