Here are descriptions for how two dot patterns are growing.
  • Pattern A: Step 2 has 10 dots. It grows by 3 dots at each additional step.
  • Pattern B: The total number of dots can be expressed by 2n^{2}+1, where n is the step number.
For each pattern, draw a diagram of Step 0 to Step 3.

Each expression represents the total number of dots in a pattern where n represents the step number.

Select all the expressions that represent a quadratic relationship between the step number and the total number of dots. (If you get stuck, consider sketching the first few steps of each pattern as described by the expression.)
