Question

Determine the domain of the function.

F(x)=x/x-9

Answer 1

Find the domain by finding where the expression is defined.

Interval Notation: (− ∞,0)∪(0,∞)

Set-Builder Notation:x

Explanation:

Answer 2

All Real x (x not = 9).

Explanation:

When x = 9, f(x) = 9/0 which is undefined.

So the Domain is All Real x, x not = 9.
