Question
Let f(x)
= x*(x - 1)3.
(a) Find the critical numbers of the function f. (Enter your answers from smallest to largest.)
smallest value
X1 =
X2 = 4/7
largest value
X3 = 1
(b) What does the Second Derivative Test tell you about the behavior of f at these critical numbers?
At x, the second derivative test indicates a local minimum
At x, the second derivative test indicates neither a minimum nor a maximum v x .
At x, the second derivative test indicates a local maximum
(c) What does the First Derivative Test tell you? Note what the First Derivative Test tells you that Second Derivative Test does not.
At x, the first derivative test indicates a local minimum
At x, the first derivative test indicates neither a minimum nor a maximum v
At x, the first derivative test indicates a local maximum
---Select---
indicates a local minimum
Enhanced Feedback
Please try again, keeping in mind t indicates neither a minimum nor a maximum hen f'(x) = 0 or f'(x) does not exist. By the first derivative
indicates a local maximum
is inconclusive
then f has a local maximum at c, al
then f has a local minimum at c. The second derivative test s
la local maximum at c.
