Lesson 4 (Domain and Range) • What is domain? • What is range? • The x values of a function. (Independent variable) • The y values of a function. (Dependent variable)
Lesson 4 (Domain and Range) • Using domain and range, functions can be expressed by tables, equations, graphs, and verbal descriptions. • Example: • y = 1 + 2x • x= first number, y= second number • The second number is one more than twice the first
Lesson 4 (Domain and Range) • Given each problem, create the other representations.
Lesson 4 (Domain and Range) • The second number is one less than twice the first.
