## How do you know if a function is bounded above or below?

Being bounded from above means that there is a horizontal line such that the graph of the function lies below this line. Bounded from below means that the graph lies above some horizontal line. Being bounded means that one can enclose the whole graph between two horizontal lines.

## What are the 4 types of functions?

The types of functions can be broadly classified into four types. Based on Element: One to one Function, many to one function, onto function, one to one and onto function, into function.

## How do you know if a graph is below a function?

Inspect the graph to see if any vertical line drawn would intersect the curve more than once. If there is any such line, the graph does not represent a function. If no vertical line can intersect the curve more than once, the graph does represent a function.

## What is a closed domain?

A closed domain system, also known as domain-specific, focuses on a particular set of topics and has limited responses based on the business problem. For example, a pizza delivery chatbot can only help you place, track, or cancel an order.

## How do you tell if a function is odd or even?

You may be asked to “determine algebraically” whether a function is even or odd. To do this, you take the function and plug x in for x, and then simplify. If you end up with the exact same function that you started with (that is, if f (x) = f (x), so all of the signs are the same), then the function is even.
