Hello there!
The answer is C.
I will explain to you how I came to this answer.
•First of all, I counted the turning points. There are two, so that means this polynomial function has THREE roots. (# of turning points+1=number of roots.)
•Next, look to see how many times the function crosses the x-axis. This is the number of REAL solutions. In this case, there is one point at which the f(x) is crossing the x-axis so there is one real solution.
•Since there is one real solution there has to be 2 imaginary roots. (Total # of solutions-real solutions=imaginary solutions)
NOTE: the turning points are where the increasing intervals change to decreasing and the decreasing change to increasing. The first derivative at these points is 0.
I hope this helps!
Best wishes~

u take x then multiply it by b, the add 9 to x then we will get the answer xb9x, hope u understand;>
Answer:
$1612.80
Step-by-step explanation:
<u>Sales Tax</u> would be 0.06 * 21,000 = $1260
<u>Property Tax:</u>
16.80 for every 1000, so how many "1000"s are there in 21,000? Simple, 21 of them.
So the property tax would be 16.80 * 21 = $352.80
Hence, total taxes (for the year) = 1260 + 352.80 = $1612.80
Answer:
For example, 16/21
Step-by-step explanation:
Are there choices?
There is an infinite number of numbers between any two numbers.
2/3 = 14/21
6/7 = 18/21
One example of a fraction between 2/3 and 6/7 is 16/21
16/21 is between 2/3 and 6/7.
