Victoria has $200 of her birthday gift money saved at home, and the amount is modeled by the function h (x) = 200. She reads about a bank that has savings accounts that accrue interest according to the function s (x) = (1.05) x - 1. After combining the two functions, the new function is g (x) = 200 (1.05) x - 1. Using complete sentences, explain what this new function means.

Bryan Berry · Answer 1

The total amount of interest that Victoria will receive (g (x)) is equal to the original amount (200$) multiplied by the rate of interest (1.05) multiplied by the time that Victoria keeps her money in the bank (x) minus one.

Sydney Grimes · Answer 2

If Victoria puts 200 dollars a savings account she will earn 1.05 for x amount of time.
