Thinkwell Vids: Verifying That Functions Are Inverses

This slideshow explains how to verify by composition that two functions are inverses of each other.

No laundry or cooking dinner here: these parent functions are all about math. Every graph you could think of from basic linear functions to the hyperbolic arccotangent function are included. With 40 parent functions, the worksheet...

Sal draws a graphical representation of a function, f(x), and builds and evaluates other functions based on that function.

Sal continues looking at function inverses in this video by showing two examples. In each example, he finds the inverse and shows the graph of both functions. His examples are with linear functions, but his first example shows a function...

This resource explains how to verify that two functions are inverses of each other.

It's not a time machine—it's a function machine! Using two rules, the video introduces a function machine that changes an input to an output. Pupils answer questions such as finding what is the input for a given output and what values...
