Answer:
2nd graph
Explanation:
Exponential increase will be a graph that increase all throughout and the rate of increase "increases" with age.
- We can rule out first graph because if you draw smooth curve along the dots, it shows increase, then decrease.
- We can rule out third graph because it is increasing BUT not exponentially, rather, at a constant rate.
- We can rule out fourth graph because it is decreasing (exponentially).
The 2nd graph is correct because it shown "increase" as well as "exponential" increase (the rate of increase increases).
Answer: 2nd graph
