Math Reflection

1) You can recognize an exponential decay pattern from a table of data if it is divided my the same number each time.

2) You can recognize an exponential decay pattern from a graph when the line slopes down.

3) You can tell that an equation represents exponential decay if the growth factor is less than 1.

4) Exponential growth relationships and exponential decay relationships are similar because they both use exponents, they have growth/decay rates, and they both have growth/decay factors. They are different because exponential growth relationships have a growth factor greater than 1, when an exponential decay's is less than 1.

5) Exponential decay relationships and decreasing linear relationships are similar because they both decrease. They are different because exponential decay relationships are divided by the same number each time, while decreasing linear relationships get the same number smaller each time.
