I would like to know how to find the equation of a quadratic function from its graph, including when it does not cut the x-axis. Thanks. Modeling This is a good question because it goes to the heart of a lot of "real" math. Often we have a set of data points from observati...
Plugging into the original equation gives: C = Y1 - AX1^2 - BX1 This all looks horrible, but we have the values for Y1, Y2, Y3, X1, X2, and X3 so we just plug them in. The example does that to find A, B, and C. It then graphs the function so you can see it passes th...
Graphs of quadratics take on the form of a U or an upside-down U. They have one maximum or minimum point called the vertex of the quadratic. To illustrate this, let's observe the actual graph of the quadratic equation representing the free throw: We see that the graph is in the ...
For my assignment on quadratic functions, I have to find the equation (the the form of ax^2+bx+c) for a table of values? The equation would be y = ax^2 + bx + c. Tris Fray Potter said: Homework Equations I know how to use vertex form and change from vertex form to standard...
An example of a quadratic function with only one root is the function x^2. This is only equal to zero when x is equal to zero. It might also happen that there are no roots. This is, for example, the case for the function x^2+3. Then, to find the root, we have to have an ...
