In mathematics, a quadratic is a type of problem that deals with a variable multiplied by itself — an operation known as squaring. This language derives from the area of a square being its side length ...

The graph below has a turning point (3, -2). Write down the nature of the turning point and the equation of the axis of symmetry. For the parabola \(y=(x+6)(x-4)\) determine the coordinates and nature ...

Use an iPad® if you want your students to graph parabolas with ease and grasp vocabulary quickly. The Free Graphing Calculator app can be downloaded to explore axis of symmetry, roots, maxima, minima, ...

Sometimes you just need to make a graph. If your TI-84 isn’t handy, Desmos Graphing Calculator is a good backup to have. The app accepts both functions and tables of x and y values as inputs and ...
