Given: f(x) = x+5 and g(x)= x - 2.
What are the restrictions of the domain of f(g(x))?
A. x=-5
B. X=-3
C. X#2
D. There are no restrictions.

Answer 1

D. There are no restrictions

Explanation:

f(g(x)) = (x-2) + 5

= x - 2 + 5

= x+3

And since x + 3 is just a line, there are no domain restrictions.
