The definition of a how to survive pc download can be extended to define the definition of inverse of a function.

Along with one to one functionsinvertible functions are an important type of function. The definition of inverse says that a function's inverse switches its domain and range. The definition of inverse helps students to understand the unique characteristics of the graphs of invertible functions. The inverse of a function. So the inverse of a function is written f little -1 of x. And careful before we go any further, I want to specify that this is not the same thing as 1 over f of x.

Normally we're used to negative exponents bringing things down to the denominator. This is a different inverse. And you're told by this notation okay? So what the inverse actually is, is the set of all points yx where xy belong to the function. Inversd that means okay, we'll put it into more simple terms, is that what does inverse mean in algebra f of x has the point 3 -1, the inverse meann going to have the the opposite, okay if you just flip your x and your y's.

So this the y would become the x value and the ij will become the y value. So the inverse is basically the set of all points so f of x is going to be a curve or have a relationship with a bunch of points. There's no switching of sign like the -1 doesn't become opposite, it just becomes the x and y values are inn or switched.
