Answer:
Step-by-step explanation: assuming you mean
f(x)=
13x - 2
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.
solve
3x - 2= 0 ⇒ x = 23 ←
excluded value
domain is x ∈, x ≠ 23(-∞, 23) ∪
(23, ∞) ←
in interval notation
graph{1/(3x-2) [-10, 10, -5, 5]}
