Advanced function types | College Algebra | Math | Khan Academy
Let's use the building blocks of simpler function types to explore functions that zig-zag or twist across the screen. Come explore the weird and wonderful world of absolute value graphs, piecewise functions, …
Function symmetry introduction (article) | Khan Academy
Graphically, a function is odd if it is symmetrical around the origin. It is called an “odd” function because polynomials with odd exponents have these properties.
Transformations of functions | Algebra 2 | Math | Khan Academy
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, …
Recognizing functions from graph (video) | Khan Academy
If any vertical line drawn on the graph passes thru only one point, then you have a function. If your vertical line can pass thru more than one point on the graph, then the graph is not a function.
