# How to write the domain and range of a graph

You can write this as x€ R or (-∞,+∞). Since y=x² is a parabola that opens up and it is tangential to the x-axis, the range is y≥0 or [0,∞). When the function is given as a graph, then the domain are

## Domain and Range of a Function From a Graph

When using interval notation, domain and range are written as intervals of values. For f (x) = x2, the domain in interval notation is: D: (-∞, ∞) D indicates that you are talking about the domain, and (-∞, ∞), read as negative infinity to positive

## Domain and Range

The range is all the values of the graph from down to up. The domain is all x-values or inputs of a function and the range is all y-values or outputs of a function. When looking at a graph, the domain is all the values of

Easy 5/5. Honestly rarely use the camera function because the calculator is incredible, it shows you the steps which has literally taught me some things that my teachers just didnt teach well enough.

Try it you will agree with me. So easy to use, normally when I type actual words into an app it gets confused but for example I typed, "f(-9) for the function f(x)=blah blah. It has providen methods t9 solve the problems and it helps from having write out everything on paper.

Determine Domain and Range from a Graph

Solution: We can see that the graph extends horizontally from -2 to 3, but the -2 is not included. Therefore, the domain is (-2, 3]. Also, we see that the graph extends vertically from 2 to -2, so the range is [-2, 2]. EXAMPLE 2 The following graph
