From yesterday…
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.
352)( 2 xxxf 013 23 xxx1.) 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 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….
