E.J. has shown that a function, f(x), grows by 12% for every unit in the domain. What does this prove? (B) The function f(x) is a geometric sequence.
Geometric sequence is defined as a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
In this case, the common ratio is 12%. Since there is growth of 12%, the previous number will be multiplied by 1.12 to get the current number.
a(n) = n*1.12
