Question

Identify the restrictions on the domain of f(x) = x+2/x-3 x≠-2 x≠2 x≠-3 x≠3

Answer 1

Answer:

  x ≠ 3

Step-by-step explanation:

The denominator of ...

  f(x) = (x+2)/(x -3)

is zero when x=3, so the function is not defined there. Values of x for which the function is not defined are not part of the domain.

The restriction is: x ≠ 3.

Please note that parentheses are required around numerators and denominators when a rational function is written in plain text. When it is typeset:

  $f(x)=\dfrac{x+2}{x-3}$

the division bar serves as a grouping symbol. In plain text, we cannot tell where numerator and denominator begin and end unless some other grouping symbol (parentheses) is used.
