There are several models of a function; some of them are linear functions, exponential functions, quadratic functions, and others.
- Set one is an exponential function.
- Set two is neither a linear function, nor an exponential function.
Set One
(x) (0) (2) (4)
f(x) (4) (1) (0.25)
Notice that, as the value of x increases by 2, the value of f(x) divides itself by a constant rate of 4
This means that:
Set one is an exponential function.
Set Two
(x) (0) (1) (2)
f(x) (5) (3) (0)
Notice that, as the value of x increases by 1, the value of f(x) does not reduce by a constant rate
This means that:
Set two is neither a linear function, nor an exponential function.
