Answer:
8
Step-by-step explanation:
When you subtract the 9-1=8
What you would need to do, is add the area of all the rectangles. The formula is wl or width * length. So find the are of all 3 rectangles, starting from the top:
5*2 = 10
3*2 = 6
5(because the rectangles are the same length)*2=10
10+10+6=26. The area of your rectangle is 26 units
A piece-wise function combines more than one functions of different input values.
<em>The value of f(-1) is -3</em>
From the graph, we have the following observations
- <em>When x = -1, y = -3</em>
- <em>When x = -1, y = -4</em>
Notice that there is a closed circle at the point where x = -1 and y = -3.
This means that y = -3 is inclusive of the values of y on that particular function
However, there is an open circle at the point where x = -1 and y = -3.
This means that y = -4 is exclusive of the values of y on that particular function
The correct corresponding value of y is when y is inclusive.
Hence, the value of f(-1) is -3
