Question

What are the domain and range of the function?

Answer 1

Answer:

Range: {0, 2, -4, -8}

Domain: {-2, -1, 0, 1, 2}

Step-by-step explanation:

The x-coordinate of each point on the graph (input values) = the domain

The y-coordinate of each point on the graph (output values) = the range

Thus:

Domain => {-2, -1, 0, 1, 2} (on the x-axis)

Range => {0, 2, -4, -8} (on the y-axis)
