Answer:
10
Step-by-step explanation:
F(x) = 3x+1, for f. 3)
3x3=9
9+1=10
Y = x
when x < -1
not equal to (≤) so no solid circle.
plot points
x | y
-1, -1
-2, -2
-3, -3
Next one is...
y = -x
when x ≥ -1
solid circle for equal to
look at points
x | y
-1, 1
0, 0
1, -1
2, -2
As you can see it's the last graph in bottom right corner.
X=0
Y=-4
I have attached a picture of the quick work to show the steps of what I did to get those answers.
The orientation of the solid is odd, but here is what I see.
24+24+39+52+65= 204 units^2
