The piecewise function all the way to the left (x + 3) should have an ending point shaded in. [At x = -2] The next function ((x^2) -1) should have both ending points left unshaded. Finally, the logarithm function should have a shaded in starting point [At x = 1] and should have an unshaded ending point at x = 3.
The first equation tells you that 
. If you substitute this expression for 
in the second, we have
And we can deduce 
Answer:
<h2>9 square units</h2>
Step-by-step explanation:
You can use the Pick's formula:
Where
- the number of lattice points inside the polygon
- number of lattice points on the border located on the perimeter of the polygon
From the picture we have:
Substitute:
E maybe not certain that it is correct, hope it helps even tho i might be wrong
One backpack = 3/4
6 backpacks = 3/4 x 6 = 18/4 = 4.5 yards
