Question

how do you state the domain and rage of a function graphed? -3,4/2,2

Answer 1

domain is all possible x values you function can have.
range is all possible y values

other than that need to see graph to give you a specific answer.

Answer 2

sorry im not good at drawing

Answer 3

if it is a straight line that keeps on going in either direction:

x can be any value ---> domain: all real numbers \((\mathbb{R})\)
y can be any value ---> range: all real numbers \((\mathbb{R})\)

Answer 4

can you give me a little eazier example

Answer 5

let's say your graph had only 3 points (1,2), (3,4), and (5,6)

domain is the set of all possible x values you function can have..
so domain: {1,3,5}

and range is the set of all possible y values..
range : {2,4,6}

Answer 6

oh ok that makes seince thanks i got it now

Answer 7

another example
in this graph , of a horizontal line segment at y=1 :
Domain: \(-2<x \le2\)
Range : {1} or \(y=1\)
