Question 390803
Put the coordinates in order first:


(-2, -8)
(-1, -1)
(0, 0)
(1, 1)
(2, 8)


Very likely that the function is {{{y = x^3}}}. How I got to this answer -- just realize that -8 = (-2)^3, -1 = (-1)^3, etc. I cannot be certain that {{{y = x^3}}} since it's quite possible to define an unusual function that satisfies all the constraints.
