Question

Select all the answers choices that would NOT be part of the domain of f o g(x) if:

Answer 1

fog(x)

$\\ \rm\rightarrowtail \dfrac{(2/x+1)+3}{4/x+1)-1}$

$\\ \rm\rightarrowtail \dfrac{2+3x+3/x+1}{4-x-1/x+1}$

$\\ \rm\rightarrowtail \dfrac{3x+5}{3-x}$

So

$\\ \rm\rightarrowtail 3-x\neq 0$

$\\ \rm\rightarrowtail x\neq 3$

Option h is correct
