Rearranging to solve for the variable you want to measure, you get a function (as long as there's not multiple outputs for any input)
Functions involve anything with an independent and dependent variable
Inputs and outputs of a function learn worked example Matching an input to a function's output (equation) A function is like a machine that takes an input and gives an output Let's explore how we can graph, analyze, and create different types of functions.
Based on this definition, a function does not need to be an equation H (x) = { (1,2) The range of a function is the set of all possible outputs the function can produce Some functions (like linear functions) can have a range of all real numbers, but lots of functions have a more limited set of possible outputs.
Functions are the equations to get an input (x) to an output (which is y or f (x))
Functions assign a single output for each of their inputs In this video, we see examples of various kinds of functions. In general, a function is invertible only if each input has a unique output That is, each output is paired with exactly one input
That way, when the mapping is reversed, it will still be a function
