Save guides, add subjects and pick up where you left off with your BBC account. All quadratic functions have the same type of curved graphs with a line of symmetry. The graph of the quadratic ...

Revise how to recognise and determine the equation of a quadratic function from its graph. BBC Bitesize Scotland revision for SQA National 5 Maths.

You can also plot graphs for trigonometric equations (equations that use sine, cosine, and tan, etc.), establish graphs for linear and quadratic inequalities, and even plot graphs for various ...

Quadratic equations are basic to algebra and are the math behind parabolas, projectiles, ... x – 1) crosses the X axis, which is where y = 0 (see graph above). In this case, ...

In other words, this parabola intersects the x-axis when x = –1 and x = 5. The same method also works for equations that are not readily factorable. That’s when students turn to the quadratic ...
