Find the Domain of (8+x)/5: Fraction Domain Analysis

Question

Select the domain of the following fraction:

$\frac{8+x}{5}$

00:00 Find the domain of assignment

00:03 Domain of assignment exists, to ensure we don't divide by 0

00:06 Meaning the denominator in the fraction must be different from 0

00:09 We will use this formula in our exercise

00:12 We can see that the denominator is different from 0

00:16 Therefore the domain of assignment is valid for all X

00:19 And this is the solution to the question

The domain depends on the denominator and we can see that there is no variable in the denominator.

Therefore, the domain is all numbers.

All numbers
