Step-by-step explanation:
Given: Piece-wise function graph.
We need to find the function.
In the graph, we can see a two-piece
For -3≤x≤0
Endpoints on graph (-3,-6) and (0,0)
It is the horizontal line. The equation of the horizontal line is y=k.
Equation: y=3
Now, we write as a piecewise function.
First blank = 2x

Answer:
2) ABCD is a RECTANGLE.
Perimeter = 30 units
Step-by-step explanation:
Here, the given points of the quadrilateral are:
A(6, –4), B(11, –4), C(11, 6), D(6, 6)
Now, if P(a,b) and Q(c,d) are any two given points, then the distance between them is given by DISTANCE FORMULA as:
Use this to find the length of all 4 sides:
AB with coordinates A(6, –4), B(11, –4) is given as:
⇒ AB = 5 units
BC with coordinates B(11, –4), C(11, 6) is given as:
⇒ BC = 10 units
CD with coordinates C(11, 6), D(6, 6) is given as:
⇒ CD = 5 units
AD with coordinates A(6, –4),D(6, 6) is given as:
⇒ AD = 10 units
Now, here AB = CD = 5 units, AD = BC = 10 units
Also, in a RECTANGLE, OPPOSITE SIDES ARE EQUAL IN LENGTH.
Hence, ABCD is a RECTANGLE.
Perimeter = AB + BC+ CD + AD = 5 + 10 + 5 + 10 = 30 units
