Answer 2

Domain: possible x values

You can see the greatest value horizontally would be 3. The least value would be -3. The line doesnt go any farther.

Solution: D = -3 < x < 3

Range = possible y values
You can see the greatest value vertically is 2 and the least value is -4.

Solution: R = -4 < y < 2

Functions need to pass the vertical line test. You can draw a vertical line and notice that it would always pass two lines, therefore it’s not a function.

Function? Answer: No
