Graph A represents a linear equation. This means that the number of tadpoles in the pond increases by a certain number every day. For example, (0,2)(1,4)(2,6) etc...
However, graph B represents an exponential equation. This means that the number of tadpoles increases by multiplying the previous number every day. For example, (0,2)(1,6)(2,18) etc... This means that this (graph B) is the correct answer.
