# MA002: Precalculus I

Unit 1: Functions   Computing postage for a package, the gasoline consumption when driving at 65 mph, or how much money will be in a savings account after five years are all examples of where functions are utilized. Functions are used to model everyday relationships between two quantities and this unit will be your introduction to this concept using words, tables, equations, and graphs.

Unit 1 will begin with defining the concept of function, domain, range, function notation, and how to evaluate and graph a basic group of functions called “toolkit functions.” You also will explore the behaviors of functions including rate of change, local extrema, and concavity. The remainder of the unit builds from combining functions using composition and transformations and ends with finding a function’s inverse. All of these skills will be used throughout the remaining units.

Completing this unit should take you approximately 28.25 hours.
