Answer 2

I can help you with finding the minimum value of a function. The function y = x^2 - 4x + 3 is a quadratic function, which means it has the form y = ax^2 + bx + c, where a, b, and c are constants. To find the minimum value of a quadratic function, we can use the formula:

$$x_{min} = -\frac{b}{2a}$$

This gives us the x-coordinate of the vertex of the parabola, which is the lowest point on the graph. To find the y-coordinate of the vertex, we can plug in the x-coordinate into the function. So, for the function y = x^2 - 4x + 3, we have:

$$x_{min} = -\frac{-4}{2 \cdot 1} = 2$$ $$y_{min} = (2)^2 - 4(2) + 3 = -1$$

Therefore, the minimum value of the function is -1, and it occurs when x = 2. You can also see this by looking at the graph of the function.
