The domain of a graph of a function is x ∈ [-8, 9] and the range of a graph of a function will be y ∈ [7, 0]
<h3>What is a function?</h3>
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a graph of a function shown in the picture.
As we can see in the graph there are two bold dots are shown which represents at these points the function value exist.
At x = -8, y = 7
At x = 9, y = 6
At x = -3, y = 0
The domain of a function is x ∈ [-8, 9]
The range of a function is y ∈ [7, 0]
Thus, the domain of a graph of a function is x ∈ [-8, 9] and the range of a graph of a function will be y ∈ [7, 0]

Answer:
eight thousand four hundred nine and eight hundredths
Step-by-step explanation:
The factors of this expression would be (x+9)(x-2). You have to find two numbers that are factors of -18 that add up to 7. These numbers would be 9 and -2:
(9)x(-2)= -18
and 9 + (-2)= 7
Your answer is C) (x-2).
Yo sup??
y=(x+4)(x-2)
to find the x intercept put y=0
0=(x+4)(x-2)
so either x=-4 or x=2
Therefore the graph intersects the x axis at -4 and 2
Lenght of x intercept=|-4-2|=6 units
y=(x+4)(x-2)
=x^2+2x-8
This is an upward opening parabola
To find the coordinates of the vertex we can apply the formula
(-b/2a,-D/4a)
b=2
a=1
D=b^2-4ac
=4-4*1*(-8)
=4+32=36
Vertex=(-2/2*1,-36/4*1)
=(-1,-9)
Hope this helps.
Convert minute to seconds (1 minute = 60 seconds), set up a proportion, cross multiply, and solve.
Proportion: 
= 
Cross multiply: 60 · 100 = 5 · x
Solve (divide both sides by 5): 1200 = x
Answer: 1200 ft
