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:
13
Step-by-step explanation:
6 - 2(-1) + | -5 |
The absolute value means take the non-negative value
6 - 2(-1) + 5
Multiply
6 +2 + 5
Add
8+5
13
That means there are 24 chairs. What you would do is multiply 8 by 3 which gives you 24.
Awnser is c I just did this
X equals 4
2+8+9+7+6
=32
6*6
=36
36-32
=4
