Question

PLEASE HELP ASAP Identify the restrictions on the domain.

Answer 1

The restrictions are the values tha tmake the denomenators 0

if I understnad correctly, we have$\frac{ \frac{x+1}{x+9} }{ \frac{x}{x+4} }$ which simplifies to $\frac{(x+1)(x+4)}{(x)(x+9)}$
denomenator is x(x+9)
set to zero to find restrictions
x(x+9)=0
set to zero
x=0
x+9=0
x=-9

restrictions are x≠0 or -9
