Question

What is the domain of the function f(x) = 1/3x + 2

Answer 1

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]}
