Question

What is the domain of f?

Answer 1

`\huge \boxed{\mathrm{A}}`

Explanation:

The domain of a function is all possible values for the value of x.

The denominator in a rational function cannot equal to 0.

`x+2\\eq 0`

Subtracting 2 from both sides.

`x\\eq -2`

The domain of the function is all real numbers except -2.
