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

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

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

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

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

Answer:

see attached

Step-by-step explanation:

For x < -6, the function has a slope of -1 and an x-intercept of -6.

For x > -6, the function has a slope of 2 and an x-intercept of -6.

The function given here is not defined at x=6, so there is a hole at (-6, 0).
