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
`( (x+1)/(x+9) )/( (x)/(x+4) )` which simplifies to
`((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
