• Domain/Range/ Function Worksheet

Warm UpFunctions

• From yesterday

• Analyzing Graphs of Functions

• Lets 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):

1.)2.)3.)Lets try #s 16, 22, 24 on page 47

• Homework, DAY 1Pg. 47 #s 21, 23, 27, 29, 97Pg. 37 #s 57- 67 odd

• Day 2 Warm Up/ReviewPg. 50 #s 98Pg. 26 #s 129-132, 134, 138

• Identifying intervals of increasing and decreasingWrite using interval notation, using x value onlyIncreasing: (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 FUNCTIONSEVEN: f(-x) = f(x)*symmetric to the y axisODD: f(-x) = - f(x)*symmetric to the originLets Practice!!!

• Homework DAY 2Pg. 48 #s 31-37 odd, 49, 51, 61-65, 67, 76

• Finding Domain and RangeLets find the domain and range of the given function using interval notation.

• Lets do some more
