(3x + 1) (2x + 7)
Factored by grouping
1 dozen = 12
Divide 941 by 12:
941 / 12 = 78.42
So the greatest number of dozens he can make is 78.
The answer is x equals -3
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.
A line segment is different from a line in that a segment has TWO END POINTS.
A line segment has two end points while a line has only one end point. Also you can measure the length of a line segment but you can not measure the length of a line, that is because it continues indefinitely.
