Answer:
domain is set of all x values except -4
Step-by-step explanation:
[tex]f(x)=\frac{x-1}{x+4}[/tex]
Domain is the set of x values for which the function is defined
When the denominator becomes 0 then the function is undefined
to find the values of x that makes the denominator 0, we set the denominator =0 and solve for x
[tex]x+4=0\\x=-4[/tex]
the value -4 make the denominator 0
so domain is set of all x values except -4
