Answer:
Range tells you how high and low the graph of this parabola goes in the “y” (vertical) directions.
1. We can see that the parabola peaks on the y-axis at y = 4. That’s as HIGH as it goes.
2. We also see that both sides of the parabola descend to the level of y = -7. That’s as LOW as it is shown to go.
So putting these together, we say the Range is given by:
-7 <= y <= 3
AMBIGUITY WARNING:
Because the two branches of the parabola go fall right down to the edge of the picture boundary, it’s UNCLEAR whether the parabola truly stops at y = -7 or CONTINUES on (to negative infinity).
In THAT case, the RANGE simplifies to:
Y <= 4
Done.

Solution:
12.5 < x < 18.9
Reason:
To solve this problem, we can apply Pythagorean's theorem.
To find the upper bound:
We can set the two given legs as the 2 legs of a right triangle. This allows us to keep the angle under 90 degrees. So if we set the legs to be 10 and 16, then the third side must be:
10^2 + 16^2 = x^2
x^2 = 356
x is roughly equal to 18.9
For the lower bound, this time, we set x as one of the legs, and 10 as the other let. Since we know that the longest side is 16, we can set up an equation again:
x^2 + 10^2 = 16^2
x^2 = 16^2 - 10^2
x^2 = 156
x is roughly equal to 12.5
So we have found the bounds to be 12.5 < x < 18.9
Geometric mean =√(45*5)=√(5*5*9)=15
Square root because we have 2 numbers.
