The sentence indicates that the increase in the value of a coin collection was exponential as such increase was continuous and constant in time. (Correct choice: A)
How to determine if a given relationship represents an exponential function
Exponential functions are trascendent expressions, these are, expressions that cannot be described algebraically, that are defined by the following expressions:
[tex]f(x) = a \cdot \left(1+ \frac {r}{100}\right)^{x}[/tex] (1)
Where:
- a - Initial value
- x - Independent variable
- f(x) - Dependent variable
- r - Increase rate
Exponential functions are used to represent constant continuous increases or decreases in terms of the independent variable. The sentence indicates that the increase in the value of a coin collection was exponential as such increase was continuous and constant in time. (Correct choice: A)
