Answer:
range of f(x) = [-4, -2) ∪ [2, 8)
a+b+c+d = -4
Step-by-step explanation:
The graph is attached. The range is the vertical extent of the function. It is defined at f(0) = -4 and f(2) = 2.
The limits f(2-) and f(4-) are -2 and 8, respectively, so the graph has open circles there. These are the ends of the two half-open intervals that make up the range of the function.
The portion of the graph in the domain [4, 7) is included in the range [2, 8), so no special treatment is needed for that piece of the function.
Answer:
A
=
b = ×
b =
then b = that is ORANGE
B
-2 - v = -7
v = -7 +2
then v = k + m that is BROWN
C
=
q =
then q = that is YELLOW
D
4m + 2(n) = 5 (n)
4m = 5 (n) - 2n
4m = 3n
m =
then m = that is RED
E
-8 = - 6
= -8 + 6
x = -5 (-8 + 6)
then x = y( w + z ) that is LIGHT GREEN
