You will learn functional notation and how the input and output of an equation/function can be related to variables and tables. You will be able to identify what is a function and how to identify one. Direct variation functions and function rules for arithmetic sequences will be learned. Each lesson is comprised of a video lesson with downloadable lesson worksheets with and without solutions and a series of graded practice exams which provide step by step solutions to every problem on the exam. Section 1 - Identify and Evaluate Functions f(x) = 2x-4 You will learn to identify and solve both singular and nested functions. You will learn how to find the domain and range of a function and how to find the constant of variation (a.k.a. the slope) of direct variation functions. Section 2 - Direct Variation Functions f(x)=mx You will use inductive reasoning to solve and write Direct Variation Functions from word problems. Contact Core Algebra 1
