Ido not understand this!

if the composition of two functions is:



find the domain restriction. show your work

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

Step-by-step explanation:

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

F(x) =

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, ∞)

80x^8−68x^6+16^5−20x^4−4x^3+8x^2

hope i'm right lol
