rational numbers can be written as a ratio of two integers a/b

1/2 is the ratio of 1 and 2 so its rational

√7/10 is not a ratio of two integers so its irrational

3π/4 is not a ratio of two integers so its irrational

5/9 is the ratio of 5 and 9 so its rational

18 is 18/1 and is the ratio of 18 and 1 so its rational

Help meee will give brainly! Find the domain of the function f(x)=5x−9 . DONT SAY I DONT KNOW

Agata [3.3K]

Answer and Step-by-step explanation:

$\frac{5}{x-9}$

The domain is all real numbers except 9 (positive)

This is because we can't have 0 in the denominator, and when x equals 9, then the denominator is 0. Anything divided by 0 is undefined, which is why 9 (in this equation) is not included.
