Question

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

Answer 1

x ≠ -4

Explanation:

Answer 2

`x \\e - 4`

Explanation:

The given function is

`f(x) = (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 \\e0`

`x \\e - 4`

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