Question

In a third area, the number of species of wildflowers is expected to grow according to the following description. “The initial amount is 1,500 and for each decade moving forward the count will increase by 200.

Is this linear or exponential? Explain.

Answer 1

Linear

Explanation:

If you graph this, you start at 1500 on the y-axis. Every time the x-axis increases by 1, the y-axis increases by 200. This forms a straight line, making it exponential since it increases by a constat amount.
