What is a function?
Function, in mathematics, an expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
The given function is
[tex]f(x)=\frac{x-1}{x+4}[/tex]
This is not defined when the denominator is zero.
Hence the restriction is on the denominator.
This implies that
[tex]x+4 \neq 0[/tex]
[tex]x\neq-4[/tex]
The restriction is that x ≠ -4 is not in the domain of the given function.
