Document Summary
Provide a generalization to each of the key terms listed in this section. Linear functions are functions, which are normally labeled f , if they are written in the following form: f (x) = mx + b. A grade, as if on a road or highway, is the slope but it"s expressed as a percent, which notes not steep a road is, which its formula is the following: If, for example, a road has a 5% grade, then that mean that the road rises 5 feet for every (horizontal) distance of 100 feet. The average rate of change is one way on how to nd a line"s slope of a function or even from any two given points, which can be expressed by the following: m. If a linear function is increasing over its given domain, then its slope will be positive. If a linear function is decreasing over its given domain, then its slope will be negative.
