The composite function is defined for all values for x(or any variable), except for....? When you have that, you can find the domain.

y idk

OK think of it this way: This function, 2/x+6, always has a definite value no matter what is x. But for one value, it will tend to infinity, meaning its undefined. What is that value?

anonymous · Answer

im reall confused

sumi29 · Answer

Alright. Tell us what happens when, in 2/x+6, you put x=-6?

anonymous · Answer

hey @sumi29  said for all values on number line 2/(y+6) will return a real value except -6 for which denominator becomes 0 and hence infinity the answer which is not feasible.
