Answer 2

f(x)=1/x
f(x) is defined for every x except 0.
(because 1/0 is undefined)
g(x)=x+3
This function is defined everywhere, because you can put any x to get a defined y.

What do you mean by f▫g? f(g(x))??
1/(x+3) will be undefined only when x+3=0, so when x=-3.

Answer 3

correction for second line: every->everywhere
