Answer 1

Answer:

except when x = 3

Step-by-step explanation:

f(x) = $\frac{1}{x-3}$

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

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

x - 3 = 0 ⇒ x = 3 ← excluded value

f(x) is defined for all real numbers except when x = 3
