What are all of the x-intercepts of the continuous function in the table?

The x-intercepts of a function are the values of the functions when y = 0.

Given the table below
   x                f(x)
  -4                 0
  -2                 2
   0                 8
   2                 2
   4                 0
   6                -2

As can be seen from the table, the y [f(x)] values are 0, when x = -4 and when x = 4.

Therefore, the x-intercepts of the continuous function are (-4, 0) and (4, 0).
