Question

Classify each representation shown below as either linear or exponential.

One person sends an email to 2 people. Those 2 people send it to 4 people, and those 4 send it to 8 people.

Answer 1

I think the problem is an example of an exponential representation.

1 person emailed 2 people
2 people emailed 2 people each, totaling 4 people
4 people emailed 2 people each, totaling 8 people

2¹ = 2
2² = 4
2³ = 8 and so on...
