A polynomial with 9 turning points has a power of 10. It must have one more power than the number of turning points.
Answer:
-20%
Step-by-step explanation:
64 to 80⬇
((64 - 80 / 64)) × 100 = 25 %
Therefore, your answer would have to be: 25% since it increased
Or you can try going with this method as well
80 to 64 ⬇
((80 - 64 / 80 )) × 100 = -20%
Therefore, for that method your answer would be-20% because it decreased
