Question

Find the domain of the function

Answer 1

x ∈ R, x ≠ 8

Explanation:

The denominator of f(x) cannot be zero as this would make f(x) undefined.

Equating the denominator to zero and solving gives the value that x cannot be

8 - x = 0 ⇒ x = 8 ← excluded value

Domain : x ∈ R, x ≠ 8

Answer 2

x¥8 is the answer to the question
