Answer:
[tex]y=x^3[/tex]
Step-by-step explanation:
The given relation is Q = {(x, y): (2, 8), (3, 27), (4, 64), (5, 125), . . .}
We can quickly recognize a pattern to write the equation of the given relation.
We can observe the following pattern among the x and y coordintaes.
[tex]8=2^3[/tex]
[tex]27=3^3[/tex]
[tex]64=4^3[/tex]
[tex]125=5^3[/tex]
We can see that the base of the powers on the right are the x-values of the relation and the values on the left are the y-values.
Hence, for any ordered pair (x,y), the equation is
[tex]y=x^3[/tex]
