## Answers ( No )

There are 3 things one must watch out for when finding domain and range…

1. Variables in the denominator of a fraction

2. Variables under even root signs

3. Logarithms

The domain and range of a line is

(-∞,∞) which means all real numbers because there aren’t any of these things in linear functions.

I hope this helps!

Best wishes 🙂
