Answer:

(-2,-3) and (2,-3).

Explanation:

It is given that x ∈ {-2, 0, 2} and y ∈ {-3, -1, 0, 3} .

The given equation is

y=1-x^2

At x=-2,

$y=1-(-2)^2=1-4=-3\in y$

At x=0,

$y=1-(0)^2=1-0=1\\otin y$

At x=2,

$y=1-(2)^2=1-4=-3\in y$

Therefore, the solution of given equation are (-2,-3) and (2,-3).
