It looks like you're trying to define a function. I believe you meant:

$F(x) = x^2 \times 2$

This function means that for every input value $x$, you square the value of $x$ and then multiply the result by 2. In other words:

$F(x) = 2x^2$

Example Calculation:

If $x = 3$: $F(3) = 2 \times 3^2 = 2 \times 9 = 18$

Would you like more details or have any questions?

Here are some related questions to explore:

1. What is the derivative of $F(x) = 2x^2$?
2. How would you find the value of $F(x)$ when $x = -4$?
3. How does the graph of $F(x) = 2x^2$ compare to $F(x) = x^2$?
4. What are the roots (solutions) of the equation $2x^2 = 0$?
5. How can you integrate $F(x) = 2x^2$?

Tip: When graphing $F(x) = 2x^2$, the "2" causes the parabola to stretch vertically compared to $F(x) = x^2$.
