Using the function concept, it is found that this sequence is a function because it passes the vertical line test.
A function relates <u>each value of the input to one value of the output</u>, hence, option b is incorrect.
- On a graph, each value of x(horizontal axis) is mapped to a value of y(vertical axis), hence, a vertical line test can be applied to determine whether the relation is a function.
In this problem:
- For each day, there is only one output, which is her balance, hence, it passes the vertical line test.
