Question

What is the domain and range for this graph?

Answer 1

Domain: -2 ≤ x ≤ 6

Range: -5 ≤ y ≤ 5

We include the equal to signs because the ending points for x and y are included in the graph!

Answer 2

Domain: -∞, ∞
range: -5,∞
(the commas mean through; ex.; -5,∞..... that means negative 5 thru infinity)
