Answer:

1. True

2. False

3. D. {2,4,9,16}

Explanation:

⭐What is a function?

  • a type of relation between an independent variable (x, domain) and a dependent variable (y, range) such that there is one x-value for every y-value.
  • however, there can be the same y-value for multiple x-values.

Therefore, #1 is a function because for every x-value, there is 1 y-value.

Therefore, #2 is NOT a function because 6 has 2 y-values, and 12 has 2 y-values.

⭐What is the range of a function?

  • the list of the y-values of the function
  • the range of the function must be in ascending order (smallest to largest)

Therefore, {2,4,9,16} is the range of #3 because it lists all of the y-values in ascending order.
