Using the graph and function concepts, it is found that:
a) The domain is ![[-5,4]](https://tex.z-dn.net/?f=%5B-5%2C4%5D)
, while the range is ![[-2,-5]](https://tex.z-dn.net/?f=%5B-2%2C-5%5D)
b) The function is increasing in ![[0,1]](https://tex.z-dn.net/?f=%5B0%2C1%5D)
and ![[2,3]](https://tex.z-dn.net/?f=%5B2%2C3%5D)
, and decreasing ![[-5,0], [1,2]](https://tex.z-dn.net/?f=%5B-5%2C0%5D%2C%20%5B1%2C2%5D)
, and ![[3,4]](https://tex.z-dn.net/?f=%5B3%2C4%5D)
.
--------------------
- 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:
- The y-values are from -2 to -5, thus, the range is:
--------------------
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.

Her error in terms of inches was 2 inches while her percent error was 4.166%
Step-by-step explanation:
Step 1; From the given data Claire estimated her brother to be shorter than he actually was. She estimated his height to be 4 feet while it was actually 4 feet 2 inches.
We convert the feet into inches because 12 inches are equal to a feet.
4 feet = 4 × 12 inches = 48 inches
4 feet 2 inches = (4 × 12 inches) + 2 inches = 48 + 2 = 50 inches
Error in terms of inches = 50 inches - 48 inches = 2 inches.
Step 2 ; Her percent error is given by dividing the difference in values by the actual value multiplied by 100.
% error = (difference in values / actual value) × 100
Claire's % error = (50 - 48)/ 48 × 100 = 2/48 × 100 = 0.04166 × 100 = 4.166%.
Answer: (36 - 1) ÷ (3 + 2) + 13 = 20
Step-by-step explanation:
PEMDAS rule calls for parenthesis to be solved first, then exponents, then multiplication or division then addition or subtraction depending on which comes first in the equation.
Using the PEMDAS rule the 20 can be gotten to if the equation is expressed as follows;
(36 - 1) ÷ (3 + 2) + 13 = 20
The parenthesis will be solved first;
35 ÷ 5 + 13 = 20
The division will be done first;
7 + 13 = 20
Then the addition;
7 + 13 = 20
