Question

PLEASE HELPPPP

2(y+a)/a(x-3)

find the restriction

Answer 1

a ≠ 0

Explanation:

You want to know the restriction applicable to 2(y+a)/a(x-3).

Undefined

A rational expression is undefined when its denominator is zero. The restrictions are applied so that no denominator is zero.

Here, the expression is ...

`(2(y+a))/(a)(x-3)`

The only denominator is 'a'. It cannot be zero.

The restriction is a ≠ 0.

Additional comment

If we assume this is a relation in which x- and y- are the only variables, there is no restriction on the relation as written.

Perhaps you intend that (x-3) be a denominator factor. Then the relation would have the restriction x≠3. Such an expression would need to be written as ...

2(y+a)/(a(x-3)) . . . . . . using parentheses around the denominator
