Question

How can you determine the domain of a relation from its graph?

Answer 1

Basically, to determine the domain of function, you need to look at the possible value of x. (what x can be)

For example: \(y = \sqrt x\)
We can see that x only can be in range of 0 or infinity, hence your domain \([0,\infty]\)

Is that clear?

Answer 2

range of 0 and infinity**

Answer 3

yes that clear thank-you
