Answer:
Closed and Bounded.
Step-by-step explanation:
Hi there!
1) Let's start by finding the values in which the function is defined. Remember that this can be rewritten:
Since every quadratic root are defined for values 
0 then, this help us to understand that we need calculate what interval this Domain is:
![D=[-2,2]](https://tex.z-dn.net/?f=D%3D%5B-2%2C2%5D)
2) Graphically speaking, the domain is closed. For the values -2 and 2 are included, and bounded.
Bounded functions have all of their points contained by some circle origin centered. Check it out below.
Answer: That is a great question.
Step-by-step explanation:
A reciprocal of the number or a certain expression is the multiplicative inverse of a certain numbers. This means that the numerator of the original number becomes the denominator of the reciprocal and the denominator of the original number becomes the numerator of the reciprocal.
In this item, the numerator is -8b and the denominator is 5b - 6. The reciprocal of the expression will then be equal to,
R = -(5b - 6) / 8b
I wouldn't use the phrase "extends from." If the leading coeff. is neg, then the graph opens downward. Without more info we do not know the max of this fn. If we did know it, we could state that the graph max is (value) and that the graph "extends downward from this value."
I really hope this helps you
