Answer:
150
Step-by-step explanations:
Since, varies directly, and x=6 is 3 times x=2, then 50*3=150
The answer would be 12/5. That's in fraction form.
As for the domain, the only restriction comes from the logarithm. The argument of a logarith must be strictly positive, so we have

As for the range, we have:
- The range of
are all real numbers - If we change to
we're translating the function horizontally, so the range remains the same - If we change to
we're stretching the function horizontally, so the range doesn't change - If we change to
we're translating the function 1 unit up, but the range is already all the real numbers, so it doesn't change.
