Question

If F(x) = x + 4 and G(y) =, what is the domain of G(F(x))?


A. x -4
B. All real numbers.
C. x 4
D. All real numbers except -4

Answer 1

depends a lot on what \(G\) is

Answer 2

g(y)= 1/y

Answer 3

then
\[g(y)=G(x+4)=\frac{1}{x+4}\]

Answer 4

you cannot divide by zero (you will explode) solve
\[x+4=0\] for \(x\)

Answer 5

I think it's D

Answer 6

It is D!! THANK U!!!

Answer 7

No problem :)
