Question

Please Help!!!!!!!!!!!!! I do not understand this!

If the composition of two functions is:


`(1)/(x-3)`


Find the domain restriction. Please show your work

Answer 1

The answer to your question is: Domain (-∞, 3) U (3, ∞) or R - {3}

Explanation:

Rational function is a function that is expressed as a fraction.

F(x) =
`(P(x))/(Q(y))`

In rational functions, Q(x) must be different from zero.

Then

x - 3 ≠ 0

x = 3

Finally

Domain will be R - {3}

or (-∞, 3) U (3, ∞)
