In this question, a piece-wise function is asked to be graphed.
Piece-wise function:
A piece-wise function is a function that has different definitions, depending on the input.
In this question, the function has three different definitions:
When x is less than -2, the definition is:
When x is between -2 and 3, inclusive, the function is:
When x is greater than 3, the definition is:
The graphic is given by the image at the end here, with the closed circle indicating the inclusive on the intervals.

Answer:
120$ altogether
Step-by-step explanation:
There are 8 teachers and they have to pay 15 dollars so do
8×15=120
or
15+15+15+15+15+15+15+15=120
931.86, if rounded to the nearest hundredth.
The slope is y=3x-7
a= y=3x-6 (or any number as long as the slope is same)
b = y=-1/3x -7
Answer:

Step-by-step explanation:
<u>Step 1: Define</u>
3|x + y|² - (xy)²
x = 3
y = -5
<u>Step 2: Evaluate</u>
- Substitute: 3|3 - 5|² - (3(-5))²
- Multiply: 3|-2|² - (-15)²
- Exponents: 3|-2|² - 225
- Absolute Value: 3(2)² - 225
- Exponents: 3(4) - 225
- Multiply: 12 - 225
- Subtract: -213
