Pretty much the way I look at it, there is one angle, and 2 sides beside it. Easiest way for me to explain.
17% are lions, 3/10 = 30% are zebras, therefore the remaining 100 - 47 = 53% of animals are tigers.
To get the extrema, derive the function.
You get y' = 2x^-1/3 - 2.
Set this equal to zero, and you get x=0 as the location of a critical point.
Since you are on a closed interval [-1, 1], those points can also have an extrema.
Your min is right, but the max isn't at (1,1). At x=-1, you get y=5 (y = 3(-1)^2/3 -2(-1); (-1)^2/3 = 1, not -1).
Thus, the maximum is at (-1, 5).

X > 90 idk if thats what u mean or not
