The zeroes of the function will be equal to ( 7, -6 ).
<h3>
What is a quadratic equation?</h3>
It is a polynomial with a degree of 2 or the maximum power of the variable is 2 in quadratic equations. It has two solutions as its maximum power is 2.
Given function:-
As we can see that the quadratic equation in the factorized form is ( x - 7 ) ( x+ 6 ) so we will equate each factor to zero.
( x- 7 ) = 0
x = 7
( x+ 6 ) = 0
x = -6
Therefore zeroes of the function will be equal to ( 7, -6 ).

About $6805.66 as I rounded it up
This question uses a dotplot graph from which you have to extract the information.
I have attached the dotplot graph in a pdf file. You can open the file to see the graph if you do not have it.
The graph shows with dots (they use this mark +) the 51 states. Every dot means that one state has the number of license drivers per 1000 residents given by the line. For example, you can see that just above the mark of 700 therer are two dots, meaning that two states have 700 licensed drivers per 1000 residents.
Now you can see that there are 5 dots "close" the 800 mark.
That means that 5 out of 51 states "seem to have close to 800 licensed drivers per 1000 residents".
The percentage is calculated as [5/51]*100 = 9.804 %, which rounded to one decimal place is 9.8%.
Answer: 9.8%
