Final answer:

The function rule relating x and y, with y being the cube of x, is y = x3. It matches the given pairs of (x,y) values: (1,1), (2,8), and (3,27).

Step-by-step explanation:

You are looking for a function rule that relates the values of x to the values of y. Given the pairs (1,1), (2,8), and (3,27), we can notice that y is the cube of x. Therefore, the function rule is y = x3.

To demonstrate this, for each value of x, you cube it to get the corresponding value of y:

  • When x = 1, y = 13 = 1
  • When x = 2, y = 23 = 8
  • When x = 3, y = 33 = 27

This confirms that the function rule y = x3 accurately describes the relationship between x and y in your given paired numbers.

F(X)=X
And for y
F(y)=x^3
