Name the coordinates of the following points
(1, 3)(2, 5)(3, 2)(4, 3)(6, 4)(4, 0)(3, 6)
You have already learned how to represent relations as tables and graphs. (Lesson 1–4)
• Use multiple representations to represent functions.
• Translate among different verbal, tabular, graphical, and algebraic representations of functions.
• function
• function rule• function table• equation
Make a Function Table
Make a function table for four different input values and write an algebraic expression for the rule. Then state the domain and range of the function.
Step 1 Create a function tableshowing the input,
rule, and output.
Step 2 The rule double anumber and subtractone translates to 2x – 1.Use the rule to completethe table.
Make a Function Table
Answer: D = {1, 2, 3, 4}, R = {1, 3, 5, 7}
Step 3 The domain is {1, 2, 3, 4}. The range is {1, 3, 5, 7}.
A. AB. BC. CD. D
A. 3x – 2Domain {28, 58, 88, 118}Range {10, 20, 30, 40}
B. 2 – 3xDomain {28, 58, 88, 118}Range {10, 20, 30, 40}
C. 3x – 2Domain {10, 20, 30, 40}Range {28, 58, 88, 118}
D. 2 – 3xDomain {10, 20, 30, 40}Range {28, 58, 88, 118}
Make a function table for the input values 10, 20, 30, and 40. Which shows the correct algebraic expression, domain, and range for the rule?Rule: triple a number and subtract 2
Use Multiple Representations
BUSINESS An assembly line produces 30 boxes per hour.A. Write an equation to find the amount of boxes it can produce for any number of hours.
Let n represent the number of boxes and h represent the number of hours.
Answer: The equation is n = 30h.
