Analyzing Graphs of Functions

Let’s find Domain and Range from equations….

Pg. 37 #’s 56-68 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):

Let’s try #’s 16, 22, 24 on page 47

Homework, DAY 1

• Pg. 47 #’s 21, 23, 27,

29, 97

• Pg. 37 #’s 57- 67 odd

Day 2 – Warm Up/Review

• Pg. 50 #’s 98• Pg. 26 #’s 129-132, 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.

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 31-37 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….
