The following graph represents the growth of an investment over several years.

If `A` dollars is the value of the investment after `n` years, then a rule for describing the growth of this investment could be

**A. ** `A = 2000 xx (1.06)^n`

**B. ** `A = 2000 xx (0.06)^n`

**C.** `A = 2000 xx 1.06n`

**D. ** `A = 2000 xx 0.06n`

**E. ** `A = 2000 + (1.06)^n`
