A scientist cools some water at a constant rate. The graph and table show
1 answer:
The correct function that matches the data in the graph is a(n) = 46-(n-1)-4 (option C)
<h3>How to choose the correct option?</h3>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.
