Answer 2

It seems like you've provided three different polynomial functions:

1. F(x) = 4x - x^2
2. f(x) = x^2 + 2x - 3
3. y = 3x^2 - x

These are all quadratic functions, which are polynomials of degree 2. Let's discuss each of them separately:

1. F(x) = 4x - x^2: This is a quadratic function that can be graphed as a downward-facing parabola. It has a leading coefficient of -1, which means the parabola opens downwards. The vertex of this parabola can be found by completing the square, and it is at (2, 4), and the axis of symmetry is x = 2.

2. f(x) = x^2 + 2x - 3: This is also a quadratic function, and it can be graphed as an upward-facing parabola. It has a leading coefficient of 1, which means the parabola opens upwards. To find the vertex, you can complete the square, and it is at (-1, -4), with the axis of symmetry being x = -1.

3. y = 3x^2 - x: This is another quadratic function with a leading coefficient of 3, meaning the parabola opens upwards and is stretched vertically compared to the standard parabola y = x^2. To find the vertex, complete the square, and it is at (1/6, -1/12), with the axis of symmetry being x = 1/6.

If you have any specific questions about these functions or if you'd like to perform any particular operations or calculations with them, please let me know!
