Find the domain of each function: g(x)= 1/x−9
defon

Answer:

x ∈ R, x ≠ 9

Step-by-step explanation:

Given

f(x) = \frac{1}{x-9}

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

To find the value that x cannot be, equate the denominator to zero and solve for x

x - 9 = 0 ⇒ x = 9 ← excluded value

Thus the domain is x ∈ R, x ≠ 9
