Answer:

The domain is the set of x-values:

  • {-4, -2, 1, 2, 4}

The range is the set of y-values:

  • {-4, -2, -1, 1, 4}

This can be a function as each x- value has exactly one corresponding y- value.

Points are

  • (-4,-1)
  • (-2,1)
  • (1,-2)
  • (4,-4)
  • (2,4)

All x values has a unique image in y so it's a function

[tex]\\ \sf\longmapsto D_f=\{-4,-2,1,4,2\}[/tex]

[tex]\\ \sf\longmapsto R_f=\{-1,1,-2,-4,4\}[/tex]
