How are the real solutions of a quadratic equation related to the graph of a quadratic function?

Question

anonymous · Answer

The solutions you get when you solve the formula are the corresponding y coordinates to your x value. So say a point on your graph is (2,3). The first number is x and the second is y. (x,y). The number you plug into your function is x,or in this case: 2. The solution to the equation when the x value is plugged in is y, or 3. Therefore, giving you a point on your graph.

What values do a quadratic equation give you?

anonymous · Answer

The real solutions are the points at which the graph of the function crosses
the x-axis.

If the graph never crosses the x-axis, then the solutions are imaginary.
