Domain/Range/ Function Worksheet Warm Up Functions

From yesterday…

Analyzing Graphs of Functions

Let’s find Domain and Range from equations…. Pg. 37 #’s even *Look at the function and recall properties such as the type of function, y intercepts, zeros, denominators, but most often THINK GRAPH!!!

What is a zero? Where f(x) = 0 (x intercept) Find the zeros of the following (without calculator): 1.) 2.) 3.) Let’s try #’s 16, 22, 24 on page 47

Homework, DAY 1 Pg. 47 #’s 21, 23, 27, 29, 97 Pg. 37 #’s odd

Day 2 – Warm Up/Review Pg. 50 #’s 98 Pg. 26 #’s , 134, 138

Identifying intervals of increasing and decreasing… Write using interval notation, using x value only Increasing: (2,4) Decreasing: (-2, 0) Constant: (0, 2)

Identify the intervals of the following: Lets do a few more on pg. 48 #’s, 34, 36

How would you find intervals of increasing and decreasing from an equation? Find the relative maximum and minimums using your calculator. 1.)2.)

EVEN AND ODD FUNCTIONS EVEN: f(-x) = f(x) *symmetric to the y axis ODD: f(-x) = - f(x) *symmetric to the origin Let’s Practice!!!

Homework DAY 2 Pg. 48 #’s odd, 49, 51, 61-65, 67, 76

Finding Domain and Range Let’s find the domain and range of the given function using interval notation….
