How to find the discriminant Discriminant of a Quadratic Equation:A quadratic equation is a polynomial equation with its highest exponent being two. We can solve quadratic equations using something called the quadratic formula, noting that the discriminant of a quadratic equation is the portion of ...
Knowing how to find the vertex of a parabola enables us to write the equation of a parabola given only limited information about it. What is the vertex of a quadratic function? The vertex of a quadratic function is the vertex of the graph of that function. Given a quadratic function in ...
The roots of a function are the points on which the value of the function is equal to zero. These correspond to the points where the graph crosses the x-axis. So when you want to find the roots of a function, you have to set the function equal to zero. For a simple linear function...
