Answer:
Pretty sure for the local maximum one of them should be either 7 or y=7. Then for the local maximum about 5 it should be 5 or y=5 and for the last part you got wrong I think it should 2 or Y=2
Explanation:
Local minimum or maximum is the lowest point or highest point. In this case the local maximum would be 7 because it is the highest and the local minimum would be 2 as it is the lowest. I think you did something wrong because of the way you wrote it so I think you should ask your teacher on how to write it out
