Question

State the domain and range of the graph below

Answer 1

For the first graph:

Domain: -∞
`\leq` x
`\leq` ∞

Range: y
`\geq` 3

For the second graph:

Domain: 0
`\leq` x
`\leq` 4

Range: y
`\leq` 64

Explanation:

For the second graph, I'm assuming that that point are stopping at (0,0) and (4,0) that's why I wrote that for the domain. If it doesn't stop, then the domain would be the same and the first graph.
