What is the domain of y= 2x - 4/x^2 - 4?

{x while x ≠2, -2}

Step-by-step explanation:

First let's define domain,

Domain is the set of all values on which the function is defined i.e. the function doesn't approach to infinity.

Given function is:

We will look for all the values of x on which the function will become undefined:

We can see that x= 2 and x=-2 will make the denominator zero as there is x^2 involved. The denominator zero will make the function undefined.

So, the domain of the function is set of all real numbers except 2 nd -2 {x while x ≠2, -2} ..

Step-by-step explanation:

The given rational expression is:

We factor this expression to obtain:

We can see that, this rational function has a hole at x=2 and a vertical asymptote at x=-2

Therefore the domain is
