Let a represent side length of larger square.
We know that area of square is square of its side length, so area of the larger square will be
.
The area of smaller square would be
.
We will use proportions to solve our given problem.



Cross multiply:



Take square root:


Since the length cannot be negative, therefore, the side length of larger square is 6 inches.

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.
