The correct function that matches the data in the graph is  a(n) = 46-(n-1)-4 (option C)

How to choose the correct option?

The only way is to verify the function matches the data by replacing n.

For example, we know at 5 seconds the temperature is 30. Let's use 5 (n) to verify the function.

  • a(n) = 46-(5-1) x 4
  • a(n) = 46- 4x 4
  • a(n) = 46- 16
  • a (n) = 30

This option matches the value of the temperature.
