Inverse graphing calculators help higher-level math students, such as those in advanced algebra and pre-calculus, visualize functions and their inverses to learn how the graphs behave.

The second way to graph the inverse function is algebraic. Start with the original equation’s function, swap x and y, and then solve. For example: f (x) = 5x +10 (original function of x) ...

Refining with colors Mathematicians have developed various strategies to compare graphs. Since the 1970s, algorithms have been able to test graph isomorphism, but in exponential time.

Practice how to recognise and determine the equation of a quadratic function from its graph ahead of your National 5 Maths exam with this interactive maths quiz.

Apart from displaying graphs of plotted equations, one of the major innovations of the graphing calculator was the ability to compute the sine, cosine and tangent trigonometric functions. Graphing ...
