Question

Does the table show a proportional relationship? If so, what is the value of (y) when (x) is 11?

Answer 1

9514 1404 393

Answer:

  no

Step-by-step explanation:

If this is a proportion, the ratio of y to x is constant. Here, we have ...

  y1//x1 = 64/4 = 16

  y2/x2 = 125/5 = 25

These are not the same value, so the table does not represent a proportional relationship.

Additional comment

The table seemingly represents a cubic relationship, so the value for x=11 would be y = 11³ = 1331
