Our main focus today was inverse functions, but lets start with a little review on even and odd functions.

REMEMBER: IFF a graph is an even function, f(x) = f(-x), and IFF a graph is odd, f(-x) = -f(x)

I’ll show you guys how to determine if a graph is even or odd in 3 different ways; Equation, Numbers and a Graph

Example #1

Now onto inverse functions

An inverse function has swapped x and y values. In this case

red (1,2), (2,4), (3,5), (5,6)

blue (2,1), (4,2), (5,3), (6,5)

REMEMBER

Example:

There's an inverse function.

Here's a random graph of a function and its inverse:

That pretty much wraps up my post. 10 days 'til pi day and 9 days 'til pi approximation day.

Don't forget to look into your DEV projects kids!

check out this snazzy link. (Not related to math by the way)

Good night to all and to all a good night.

next scribe is ale because it's like kale divided by k
