Help meee will give brainly! Find the domain of the function f(x)=5x−9 . DONT SAY I DONT KNOW
1 answer:
Answer and Step-by-step explanation:
The domain is all real numbers <u>except</u> 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 <u>not</u> included.
