Answer 2

It looks like you've provided a function $F(x) = 8x^2 - x^4$ and specified that $x$ belongs to the interval $[-1, 2]$. How can I assist you with this function or interval? Are you looking for specific values of $F(x)$ within this interval, the critical points, the maximum and minimum values, or something else? Please provide more details so I can give you the information you're looking for.
