An error on math 104 2011 final

Do you mean question 1e ? If so, how can root 2 (plus or minus) be the max??? Both clearly are x-intercepts... And if you are talking about the y-value of the maximum, then, it doesn't make sense either since at those, the value is 1 (for max) and -1 for min.

So, really not sure where there is a mistake... I also looked at question 2 e and cannot see any mistake there either.
