Problem 111 of 7
Estimate turning points from polynomial graph features a quartic function has a local minimum at (-3,-5), a local maximum at (0,2), and another local minimum at (3,-5).
Using a hint is okay. It just tells the trainer to give you a little more review.

Your answer is equivalent to the expected form.
Walkthrough
Full solution stays hidden until you ask for it.
1. Locate where the graph changes from increasing to decreasing or vice versa.
2. Classify each change as maximum or minimum.
3. Estimate coordinates from the graph scale.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Intercepts that are not local extrema.
