So than i understand it right and this 4 turning points mean 4 corners so from this result that this polynomial has minimum 360 degrees
hope this will help you
I think it's D because you times everything from the left column to the right column
238 rounded to the nearest ten would be 240 because 8 is bigger than 5. So since its bigger we move the tens place (3) a number ahead (4).
Thats how we get 238 rounded to the nearest ten would be 240.
Hope I helped ya!!
