Answer:

B {1, 2, 3, 4} is the right answer

Skills needed: Domain vs Range, Set Values

Explanation:

1) Each function has an input and output

  • The input is the values from which the arrow starts from
  • The output is the values that the arrow points toward

2) The inputs are the x-values, and the outputs are the y-values

  • Domain is measure of all x values, Range is measure of all y-values

3) Here, the domain is the x-values (on the left side)

They are:

1

2

3

4

Which means the domain is {1, 2, 3, 4} ---> This is option B
