HOW TO KNOW IF A QUESTION IS TALKING ABOUT THE 𝑥-VALUE OR 𝑦-VALUE OF AN EXTREMUM
When asked "where" does 𝑓𝑥 have extrema, answer with an 𝑥-value.
When asked for the extrema of 𝑓𝑥 answer with a 𝑦-value.
If you aren't sure, you can play it safe and tell me "The absolute maximum is 𝑓2=1." This way, you covered all your bases and to me it just looks like you were showing your work. If you give it as the point 2,1 I won't be as forgiving.
