Answer: linear function with a negative rate of change
Step-by-step explanation:
A linear function is of the form [tex]y=mx+c[/tex] where x is a independent variable and y is a dependent variable . Here the dependent variable increase ( or decrease)c with a constant rate of increase (or decrease).
An exponential functionis a mathematical function of the form [tex]y=Ab^x[/tex] where x is a independent variable, and A is a constant called the initial value of the function. Here the dependent variable increase ( or decrease)c with a constant ratio or percentage.
Given: $1000 is taken out of a bank vault each day and nothing is added back.
So the money in the bank vault decreasing by a constant rate of $1000.
Thus, this shows linear function with a negative rate of change models the situation.
