Use completed-square form f(x)=(x-3)^2+2 to identify the maximum or minimum value.
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. Read the vertex from a(x-h)^2+k.
2. Use the sign of a to decide maximum or minimum.
3. State the extreme value k and where it occurs.
Use the worked steps, then substitute the final answer back into the original relationship to confirm it satisfies the prompt.
Giving the vertex as only an ordered pair when the prompt asks for the extreme value.
