If you have trouble remembering how to graph different mathematical functions, these simple figures with their dancing arms can help. At the very least, they’ll make you think of math every time ...

Instead of writing Function = multiply by 3 we can use algebra. Graphically, \(f(x) = x^2\) is the same as the graph of \(y = x^2\). Writing graphs as functions in the form of \(f(x)\) is useful ...
