Answer:
D 100% d
Step-by-step explanation:
Find the concavity changes of f(x).
Give the x-coordinates.
So, the answer to the multiple choice question is -1 and 5 since those points are where f''(x) changes sign.
Note: You can tell that you're supposed to find the concavity changes of f(x) and not f''(x) because from the graph it's obvious that the concavity of f"(x) doesn't change.
Answer:
20÷25
Step-by-step explanation:
20÷25=0.8
0.8 as a fraction is 8/10 which can be simplified down to 4/5
25 and 20 both go into 5. so that means that we know the numerator is 5. how many 5's go into 25? 5. how many 5's go into 20? 4. so we know it's 4/5
