Your question is a little ambiguous, but I am assuming that you meant to say the function 
Thus, I am solving your question based on assuming the function such as

But, it would still clear your concept, no matter what the function is.
Answer:
we conclude that

The graph is also attached.
Step-by-step explanation:
Given the function

We know that the domain of a function is the set of input or argument values for which the function is real and defined.
As the function has no undefined points nor domain constraints.
Thus, the domain is

Therefore, we conclude that

The graph is also attached.
< = more than
> = less than
So therefore,
D > 5 miles
Hope this helped !
Answer:
75
Step-by-step explanation:
For non-normal distributions, we use Chebyshev's Theorem.
Chebyshev Theorem
The Chebyshev Theorem states that:
At least 75% of the measures are within 2 standard deviations of the mean.
At least 89% of the measures are within 3 standard deviations of the mean.
An in general terms, the percentage of measures within k standard deviations of the mean is given by
.
In this question:
Within 2 standard deviations of the mean, so 75%.
Answer:
x=-4,4,-3,3
Step-by-step explanation:
<u>Factor</u><u> </u><u>by</u><u> </u><u>the</u><u> </u><u>difference</u><u> </u><u>of</u><u> </u><u>two</u><u> </u><u>squares</u>



Therefore, our answer is x = -4,4,-3,3
