Question

Identify the restrictions on the domain of f(x) = quantity x minus 1 over quantity x plus 4.

Answer 1

Answer:

$x \ne - 4$

Step-by-step explanation:

The given function is

$f(x) = \frac{x - 1}{x + 4}$

This is not defined when the denominator is zero.

Hence the restriction is on the denominator.

This implies that

$x + 4 \ne0$

$x \ne - 4$

The restriction is that x=-4 is not in the domain of the given function.
