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!

Answer:
$297.50
Step-by-step explanation:
If she earns 105 for three hours, she would be earning $35 an hour.
105/3=35
If she works 8.5 hours, to find the amount you would multiply the hourly rate ($35) by 8.5. So, the answer is
8.5x35=$297.50
First get n's by them selves
-6 = 10n -4n (remember to always change sign when crossing the equals sign.
-6 = 6n ( subtract and take sign of the larger) ( then divide both sides by 6 to solve for n)
-1 = n
hope this helps
Answer:
D. A sequence with 5 terms that starts with 3 and has a common ratio of 2
The GCF is 5 so the new expression would be: 5(x+2)
