Question

domain and range A) D: (–7, –2], (–1, 3] R: (–10, 9.2] B) D: [–7, –2], [–1, 3] R: [–10, 9.2] C) D: (–7, 3] R: (–10, 9.2] D) D: (–7, –2), (–1, 3) R: (–10, 9.2)

Answer 1

`\Large \boxed{\mathrm{C) \ D: (-7, 3] \ R: (-10, 9.2]}}`

Explanation:

The domain is the set of all possible x values.

The range is the set of all possible y values.

For the domain, we observe the graph, the graph will contain all the x values shown on the x-axis.

`\mathrm{D= (-7,3] }`

For the range, we observe the graph, the graph will contain all the y values shown on the y-axis.

`\mathrm{R= (-10,9.2] }`
