Problem 1

Domain:   [-3, 5)

Range:    (-4, 3]

The domain is the set of allowed x inputs, while the range is the set of allowed y outputs. For problems like this, we just list the smallest and largest values possible. In this question, the left most point happens when x = -3 and the right most point is when x = 5, but we don't include this value due to the open hole. So that's why we have a curved parenthesis as part of the domain here. The range is a similar story, but we look at the y values instead.

==========================================

Problem 2

Domain:   [-2, 4)

Range:    [-2, 5)

We aren't including any of the endpoints due to the open holes. Be sure not to mix this notation up with ordered pair notation.

===========================================

Problem 3

Domain:  [1, 4]

Range:   [-4, -1]

We include each endpoint because of the filled in circles, so that's why we use square brackets here.

Answer:

The mean is: 85

Step-by-step explanation:

First you need to add everything up :

1 * 2 = 2

2 * 1 = 2

3 * 3 = 9

4 * 5 = 20

5 * 4 = 20

6 * 3 = 18

7 * 2 = 14

(I multiplyed them all first because i was fast than doing 4+4+4+4+4 because its the same as 4 * 5)

then add them all up 2+2+9+20+20+18+14=85

Answer:

The median is: 4

Step-by-step explanation:

Get the data in NUMERICAL ORDER (smallest to largest), then eliminate the extremes until we're at the middle. (basically chopping off the end till you get to the middle)  Therfore The answer would be 4.

Answer:

The mode would be: 4

Step-by-step explanation:

The mode is Get the data in NUMERICAL ORDER, and see which value is the most frequent (we can have more than one mode).

Answer:

25%

Step-by-step explanation:

firs you do 5 divided by 20 because there are 20 x's. this will = 0.25

0.25 = 25%

I hope I get brainiest. Sorry for taking forever. Have a nice day!
