23 Nancy works for a company that offers two types of savings plans. Plan A is represented on the graph below.

Plan B is represented by the function f(x) = 0.01 + 0.05x^2, where x is the number of weeks. Nancy wants to have the highest savings possible after a year. Nancy picks Plan B. Her decision is

(1) correct, because Plan B is an exponential function and will increase at a faster rate

(2) correct, because Plan B is a quadratic function and will increase at a faster rate

(3) incorrect, because Plan A will have a higher value after 1 year

(4) incorrect, because Plan B is a quadratic function and will increase at a slower rate
