Lesson 2b – Functions and Function Operations Mini-Lesson Problem 10 MEDIA EXAMPLE – FUNCTION DIVISION For each of the following, determine f (x) . Use only positive exponents in your final answer. g(x) a) f(x) = 10x 4 + 3x 2 and g(x) = 2x 2 b) f(x) = -12x 5 + 8x 2 + 5 and g(x) = 4x 2 Problem 11 YOU TRY – FUNCTION DIVISION For each of the following, determine f (x) . Use only positive exponents in your final answer. g(x) a) f(x) = 25x 5 – 4x 7 and g(x) = -5x 4 b) f(x) = 20x 6 – 16x 3 + 8 and g(x) = -4x 3 Scottsdale Community College Page 82 Intermediate Algebra
Lesson 2b – Functions and Function Operations Mini-Lesson Functions can be presented in multiple ways including: equations, data sets, graphs, and applications. If you understand function notation, then the process for working with functions is the same no matter how the information if presented. Problem 12 MEDIA EXAMPLE – WORKING WITH FUNCTIONS IN TABLE FORM Functions f(x) and g(x) are defined in the tables below. Find a – h below using the tables. x -3 -2 0 1 4 5 8 10 12 f(x) 8 6 3 2 5 8 11 15 20 x 0 2 3 4 5 8 9 11 15 g(x) 1 3 5 10 4 2 0 -2 -5 a) f(1) = b) g(9) = c) f(0) + g(0) = d) g(5) – f(8) = e) ( ) ( ) Problem 13 YOU TRY – WORKING WITH FUNCTIONS IN TABLE FORM Given the following two tables, complete the third table. Show work in the table cell for each column. The first one is done for you. x 0 1 2 3 4 f(x) 4 3 -2 0 1 x 0 1 2 3 4 g(x) 6 -3 4 -2 2 x 0 1 2 3 4 f(x) + g(x) ( ) ( ) ( ) ( ) Scottsdale Community College Page 83 Intermediate Algebra
