In _______________, the unit of measure for the output of function f must be identical to the unit of measure for the input of function g.

### quadratic functions

Form the third family of functions that exhibit only a single type of concavity over the entire input interval. Differ from exponential and logarithmic functions in that they also exhibit a change of direction. Are increasing over a portion of their unrestricted input interval and decreasing over another portion of their unrestricted input interval.

### logistic function

In many situations, forces ultimately limit growth. In this case a _______________ would increase toward an upper limit. In other contexts, __________________ can describe a decline toward a lower limit.
