domain and range help

[chutch82]

find the restrictions on the domain and range for:
y=square root of 6-2x

find the restrictions on the domain and range for: y=square root of 6-2x

There are no square roots of negative numbers.
SO \(\displaystyle 6-2x\ge 0.\)

 

[lookagain]

find the restrictions on the domain \(\displaystyle > \ > \ \)and range \(\displaystyle \ < \ < \)for:
y=square root of 6-2x

\(\displaystyle y \ = \ \sqrt{6 - 2x}\)


Range:

What is the smallest y-value?

What is the largest y-value?

Are there any gaps (intervals of y-values) where
there is no graph, that the expression is undefined?
