Step-by-step explanation:
<u>Step 1: Distribute</u>



<u>Step 2: Add 6 to both sides</u>


<u>Step 3: Subtract 2x from both sides</u>


<u>Step 4: Divide both sides by 10</u>


Answer: 
Using function concepts, it is found that the correct option is given by:
a.Yes, this graph represents a polynomial. There are two turning points and the least degree possible is three.
<h3>What is the least degree possible of a polynomial?</h3>
Supposing a polynomial with n turning points, the least possible degree is of n + 1.
In this problem, the polynomial has 2 turning points, hence the least possible degree is of 3 and option a is correct.

I would believe that the answer is 20,00 because i like to use the saying 5 or above give it a shove, for or less let it rest. So you use this saying for the number behind the number it says to round to. Which in this case is 4 so because according to the saying it says let it rest if the number is 4 or less. So that is how i got my answer :D Hope you understand now!!!
