This topic covers: - Intercepts of linear equations/functions - Slope of linear equations/functions - Slope-intercept, point-slope, & standard forms - Graphing linear equations/functions - Writing linear equations/functions - Interpreting linear equations/functions - Linear equations/functions word problems
Equations and functions are not the same thing, but they can be related in several ways. Watch Jesse Roe and Sal talk about the difference between equations and functions.
In this unit, we learn about functions, which are mathematical entities that assign unique outputs to given inputs. We'll evaluate, graph, analyze, and create various types of functions.
Learn why we'd want to compose two functions together by looking at a farming example. Cam is a farmer. Each year he plants seeds that turn into corn. The function below gives the amount of corn, C , in kilograms (kg), that he expects to produce if he plants corn on a acres of land.
