Equations vs. functions - Khan Academy
Functions essentially talk about relationships between variables. You get one or more input variables, and we'll give you only one output variable. I'll put value. And you can define a function. And I'll do that in a second. You could define a function as an equation, but you can define a function a whole bunch of ways.

Transformations of functions | Algebra 2 | Math | Khan Academy
We can think graphs of absolute value and quadratic functions as transformations of the parent functions |x| and x². Importantly, we can extend this idea to include transformations of any function whatsoever! This fascinating concept allows us to graph many other types of functions, like square/cube root, exponential and logarithmic functions.
