two numbers are not in the domain of fºg?
Separate your answers with a comma.
Enter the correct answer.

Answer 1

Answer: the answer is not 0,6 it’s 0,-6. It’s right I took the test.

Explanation:

Answer 2

Explanation:

f°g=
`f(g(x))`

`g(x)=x^2-6x`

`f(x)=1/x`

`f(g(x))=`
`(1)/(x^2-6x)`

if the denominator is zero the number is undefined which makes it not in the domain of the function

set
`x^2-6x` equal to 0

the values for x is 0 or 6

so the only value that is not in the domain of f°g is 0 and 6

Hope that helps :)
