Question

What is the domain of the following function?

Answers:

x < 3

x ≤ -3

x > 3

x ≥ -3

Answer 1

take a look at the x-values, where does the graph start?

Answer 2

It started at (-3,-1)

Answer 3

good, that means the smallest x value is -3

now, if you look at the endpoint of the graph, you'll see that it's a closed circle, so we use ≥ and not >

so our domain is x ≥ -3

Answer 4

Thank you!!
