In this graph, 𝑥 and 𝑦 are directly proportional. This means that when 𝑥 doubles, 𝑦 also doubles, and when 𝑥 triples, so does 𝑦. In fact, for all coordinates on this line, you ...

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

Exponential functions are commonly used to model phenomena such as population growth, the spread of coronavirus, radioactive decay and compound interest. Logarithmic functions, the inverse of ...

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) ...
