Final answer:
The zeros of the function y=x²-1 are x=1 and x=-1.
Step-by-step explanation:
The zeros of the function y=x²-1 can be found by setting y equal to zero and solving for x. In this case, we have the equation x²-1=0. To solve for x, we can add 1 to both sides of the equation to get x²=1. Taking the square root of both sides, we obtain x=±1. Therefore, the zeros of the function are x=1 and x=-1.
