Agenda (1) Finish Graphing Square Root Functions (25-1) (2) Simplifying Rational Expressions (3) Closure
25-1 Graphing Square Root Functions Pg. 388 What if we have a number on the inside of the square root? What type of change does it create? Ø In the My Notes Column, graph the parent f(x) in one color. Ø As a class we will plot the points for g(x) using a table. Ø Under (a) describe what type of transformation appears to have been made.
25-1 Graphing Square Root Functions Stretch to get closer to Compression to go away from y = a b(x h) + k Horizontal Stretch if (1/b) > 1 Comp. if 0<(1/b)<1
25-1 Graphing Square Root Functions Practice: Graph the following. Describe transformation.
25-1 Graphing Square Root Functions Pg. 388 What if we have a negative on the inside of the square root? What type of change does it create? Ø We will airst rewrite the inside such that the b value is isolated. Ø Graph the parent f(x) on #5. Ø We will graph g(x) using a table. Ø Describe the transformations.

Notebook! I will leave one page blank for my next set of SB notes. Today s Lesson #: 29-1/29-2 Topic: Simplifying Rational Expressions LO#4: Perform operations involving rational expressions.
Pg. 445 The remainder of the period is about rational expressions! Discuss with your horizontal partner: What is a rational number?
Pg. 446 We will do Try These A (a) in the My Notes Column following the steps SB provides. Do (b-c) in your groups. (4 mins)
Discuss with your Vertical Partner: Discuss with your Horizontal Partner:
Pg. 447 We will do Try These B-C (a-b) in the My Notes Column following the steps SB provides.
Pg. 447 We will do Try These B-C (a-b) in the My Notes Column following the steps SB provides.
Pg. 447 With your vertical partner the following question: Why is it important to state the restrictions even if the problem doesn't t ask for it? Do #4-5 independently. (3 mins) Discuss your solution with your tablemates. (30 secs)
Now lets add and subtract rational expressions! Lets start with the basics: Whiteboards!
In order to solve rational equations (which we will do in the future) we need to aind the LCD Least Common Denominator.
Pg. 449 We will do Try These A as a class.
Pg. 449 Do the following extra problems in the My Notes Column. Find the LCD. (a) (b)
Pg. 450 We will do Try These B (a) as a class.
Pg. 450 Do the indicated problem. (3 mins) Green dots (b) Blue dots (c) Red dots (d) Yellow dots (f) Find 3 others with the same color as you and compare solutions. If you got it wrong, help one another aigure out the solution. (1 min)

Pg. 451
Pg. 451 We will do Try These C (a) as a class.
Pg. 451 Do Try These C (b) in your groups.
Exit Ticket In your own words, why do we have to identify the restrictions on x?
