The quadratic equation y = -x^2 - 4x - 3 has a degree of 2
The vertex of the function is (-2,1)
<h3>How to graph the function?</h3>
The equation of the function is:
y = -x^2 - 4x - 3
Differentiate
y' = -2x - 4
Set to 0
-2x - 4 = 0
Solve for x
x = -2
Substitute -2 for x in y = -x^2 - 4x - 3
y = -(2)^2 - 4(-2) - 3
y = 1
The above means that the vertex of the function is (-2,1)

Formula for the area of a trapezoid:
0.5 x h x (b + a)
b = 6 + 3 + 3 = 12
h = 8
a = 6
0.5 x 8 x (12 + 6)
4 x 18 = 72
A = 72 square units
8 inches
It's asking about inches so first, you need to convert the feet into inches
So multiply 4*12=48
1/2*48= 24
2/3*48= 32
32-24= 8
