Step-by-step explanation:
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)

Answer:A) 4√5
Step-by-step explanation:
The formula for determining the distance between two points is expressed as
d = √[(x2 - x1)^2 + (y2 - y1)^2]
Where
d is the distance between the two points.
x2 represents the final value of x on the horizontal axis.
x1 represents the initial value of x on the horizontal axis.
y2 represents the final value if y on the vertical axis.
y1 represents the initial value of y on the vertical axis.
From the information given,
y2 = 8
y1 = 4
x2 = -5
x1 = 3
d = √[(- 5 - 3)^2 + (8 - 4)^2]
d = √(-8^2) + 4^2 = √64+16
d = √80
d = 4√5
