Question

Can you help me with this one it has trhyree parts

Answer 1

Given: A graph showing point A, B, and C

To Determine: The nature at f, f', and f''

Solution

`f=negative`

At turning point, the first derivative is zero. Therefore

`f^(\prime)=Zero`

The minimum point is the test for the second derivative. Hence, the second derivative is

`f^(\prime\prime)=Positive`

In Summary

f = negative

f' = zero

f'' = positive
