What are they?
They * reverse the operations done by a function*. When plotted, it’s the mirror of a function across the line. Not all functions are invertible, only one’s that pass the horizontal line test (I.E. One-To-One). It turns to .
To Find:
To get the inverse, replace the function’s x’s with y’s and then solve for y instead. Alternatively, if you’re given a value that the equals, say 22, just think really hard about about function satisfies that.
