Question

Identify one characteristic of exponential growth.

A. A graph that is an increasing curve
B. A common ratio between 0 and 1
C. A common ratio less than 0
D. A common difference greater than 0

Answer 1

A. Exponential growth is called growth because it increases, so A is correct.
B. A common ratio between 0 and 1 would result in decay, not growth
C. A common ratio less than one would just reflect the graph across the x-axis. It does not give any information about whether or not it is exponential growth.
D. Exponential growth functions have no common differences.

Thus, A is the correct answer.
