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

Answer:
A) 106 ft^2
Step-by-step explanation:
The total surface area is the area of the base triangular face and the three lateral faces.
The base triangular face has length of its base to be b=6 ft.
The height of this triangle is 5.2 ft.
The area of this triangle is
to the nearest integer
The area of the three lateral face is
The total surface area is therefore 90+16=106 square feet
