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~

Answer:
The total money in account after 8 months is $72 + $8 x
Step-by-step explanation:
Given as :
Total money available in saving account = $72
The money saves each month in account = $x
So, The money saves in account after 8 months = $x × 8 = $8 x
Let The total money in account after 8 months = $A
Or, A = money available in saving account + money saves in account after 8 months
i.e A = $72 + $8 x
So, The total money in account after 8 months = A =$72 + $8 x
Hence, The total money in account after 8 months is $72 + $8 x Answer
