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
Explain mathematic problems

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

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
