Using the graph and function concepts, it is found that:
a) The domain is
, while the range is ![[-2,-5]](https://tex.z-dn.net/?f=%5B-2%2C-5%5D)
b) The function is increasing in
and
, and decreasing
, and
.
--------------------
- The domain of a function is given by it's input values, that is, the values of x, the horizontal axis on the <em>graph</em>.
- The range of a function is given by it's output values, that is, the values of y, the vertical axis on the <em>graph</em>.
- If the <em>graph </em>is pointing upwards, the function increases.
- If the <em>graph </em>is pointing downwards, the function decreases.
--------------------
Item a:
- On the graph, the x-values are from -5 to 4, thus the domain is:
![[-5,4]](https://tex.z-dn.net/?f=%5B-5%2C4%5D)
- The y-values are from -2 to -5, thus, the range is:
![[-2,-5]](https://tex.z-dn.net/?f=%5B-2%2C-5%5D)
--------------------
Item b:
- On the graph, it is pointing upwards on the following intervals, for x-values: From 0 to 1, and from 2 to 3, thus, the function is increasing in
and
. - On the other intervals,
, and
, the function is decreasing.

Answer:
d
Step-by-step explanation:
1 cm = 20 feet
the triangle's sides are 4 cm, 5 cm, and 6 cm
multiply the amount of cm with 20 feet
4(20) = 80 feet
5(20) = 100 feet
6(20) = 120 feet
Simplify, divide 10 from all numbers
80/10 = 8
100/10 = 10
120/10 = 12
8, 10, 12 is your answer
hope this helps
