In this chapter, piecewise functions and step functions are graphed using tables of values. The inverse of a function is defined and found numerically and algebraically.
Piecewise functions are functions that are separated into different rules depending on the domain. This chapter shows how to graph such functions by using a table of values. A step function is a specific type of a piecewise function where each rule is a constant value. This is what gives them their specific look.
The chapter also discuss inverse functions and how to find them by switching the x and y variable and then solving for y. For example, to find the inverse of x squared, we change the x and y value and solve for y which produce its inverse which is the square root of x.
Mathleak's eCourses is a digital curriculum written for the Common Core State Standars (CCSS). Any teacher can use our eCourses either as a stand-alone curriculum or as a supplement to their current textbooks. Our courses include theory with animated instructions, problem solving exercises with answers, hints and solutions, practice tests, videos, and printable worksheets. It can also be used to supplement homeschoolers or tutors when working with students.
