Step-by-step explanation:
The domain of a function is all of the values that can be under that specific function. In this case, we're asking what values of allow to exist.
In order for square roots to exist, the quantity under the square root must be greater than or equal to , because you can't take the square root of a negative number. Therefore, we can write the following inequality to solve for :
Solving this inequality, we get:
(Subtract from both sides of the inequality to isolate )
(Multiply both sides of the inequality by to get rid of 's coefficient)
Hope this helps!

Answer:
4 : 1
Step-by-step explanation:
Each segment joining midpoints is called a "midline." It is parallel to the segment not being joined, and is half its length. All the dimensions of the smaller triangle are half those of the larger triangle. (They are similar triangles.) The ratio of areas is the square of the ratio of side lengths:
2² : 1² = 4 : 1 . . . . . . ratio of triangle areas
