1/x
X+5/x+5
X^2/x
7/(x-2)


Sagot :

Using it's concept, it is found that the domain for the expressions is, respectively, given by:

[tex]x \neq 0, x \neq 0, (-\infty, \infty), (-\infty, \infty), x \neq 2[/tex]

What is the domain of a function?

It is the set that contains all possible input values.

In a fraction, the denominator cannot be zero, hence:

  • The domain of the first two expressions is of [tex]x \neq 0[/tex].
  • The domain of the last expression is of [tex]x \neq 2[/tex].

The third expression can be simplified, as:

(x + 5)/(x + 5) = 1.

The same is true for the fourth, as:

x²/x = 1.

Neither has any restriction, hence their domain is all real numbers, represented by [tex](-\infty, \infty)[/tex].
