Answer:
x intercepts are at -2 and 2.
Explanation:
y=(x+2)(x-2) is the same as the function provided.
In this factored form, you can see where y = 0 >>> either x is -2 or 2.
Another way:
If you set y = 0, the equation becomes:
0 = x^2 - 4
4 = x^2
So either 2 or -2 satisfy this equation.
Or you can graph it, if graphing calcs are allowed.
