The domain of (bºa)(x) is all real number
Step-by-step explanation:
Given
[tex]a(x) = 3x+1\\b(x) = x-4[/tex]
We will find the composition first
so,
[tex](boa)(x) = 3x+1-4\\= 3x-3[/tex]
As there is no denominator involved in the functions, there will be no input that will approach the function to infinity so the function will be defined on all real numbers
So,
The domain of (bºa)(x) is all real number
