Warmup to 4.2--Everyone try these

Warmup to 4.2

Question 1:  Go to www.wolframalpha.com and graph the following function:

f(x) = x^2 (x-2)

Part a: How many x-intercepts are there? What are they?

Part b: Which statement is true about the graph.

a.        The graph increases on the interval (2,∞)

b.      The graph is decreasing on the interval (-∞, 0)

c.       The graph crosses through the point (0,0)

d.      The graph touches at the zero (2,0)

Question 2: Look at the following graph and answer the questions below about the attributes of the graph.

 http://www.wolframalpha.com/input/?i=f%28x%29%3D3x^5-4x^3+%2Bx^2%2Bx-1

 Part a: How many x-intercepts are there? What are they? (hint look under the graph and see if you can  tell)

Part b: Is the graph smooth and continuous? (look in your book to read about what this means)

Part c: How many turning points are there in the graph?  (look in your book to read about what this means.)

Question 3: Go to www.geogebra.org  and try to draw a graph that matches with the following description. Write down the function you found that fits this description.

This graph’s end behavior is negative from both the left and right side. This graph has 3 turning points.  This graph has two x intercepts.

I'll post the answers over the weekend.

HW, Quizzes, and Tests.

Since I never seem to have time in class I wanted to address important issues regarding homework, quizzes, and exams. 

Homework:  Stay ahead of the schedule. Don't wait a week to finish your homework. The week due date was only established to help those who have extenuating circumstances. You should plan on completing your homework before we discuss the next section. So before next tues you should have 3.5 and 4.1 completed.


Exams: We also expect you to take the exams within the first 3 days as well. So you should plan on taking the exam next week.

Quizzes: We also expect you to attend your labs. You will be given a password during lab so that you can access the quizzes. Currently the passwords have been lifted but this will not be the case starting next week. It is considered cheating to give passwords to other students. if you have something come up and can't attend any of your TAs lab sessions, please email your TA and let them know. They will make the call on whether or not they will give you the password. 

This class is challenging when you get behind, so stay focused and on top of your studies.

If you just added read here

If you just added, please take the time to get caught up and get your questions answered. Most of your questions can be answered by reading the posts on this blog. Also, if you haven't emailed Jim Logan you need to do this asap.

If you just added you will need to email Jim Logan the following information:

loganj@math.byu.edu

Name,

sec,

net id

byu id,

class that transferred out of (if applicable)

He will be able to give you access to your online homework and quizzes. We will keep the assignments open for another week to accommodate those that have transferred into our class.

Watch videos on factoring, graphing, etc. Link here

Watch videos that will help you with each section from our class. Pete's blog was put together last semester. Use his site to watch videos for each section. You might have to look at older posts. Based on students comments last semester, they found these extremely helpful.
I also have a link to pete's blog found on the quick links.

Help Session tomorrow-Be there

Hey everyone,
If you felt at all nervous about factoring, completing the square, transformations, quadratics or if you want to start studying for the test that's opening next week, come to the help session.

173 TMCB, from 1 - 4 pm tomorrow
Friday, Sept 2nd

If you can only show up for part of the time, that's just fine.
Oh and don't forget to guess how much candy is in my jar. You could win an x number of delicious m&m's.

Be sure to print a practice test from the department website here:
