NOTE: A good scribe post is fun to read, an excellent scribe post becomes famous =)
Here are the questions that were on the board and we had to answer these questions.
Plot the points on your calculator and then figure out if the functions create a straight line or curved line.
enter the x column in L1, the f(x) column in L2, g(x) in L3 and h(x) in L4
Next, press [2nd] [y=]
select plot 1 and press enter. turn plot 1 on by pressing enter, here you can select how the points will be plotted (i.e. dots, dotted lines, lines).
You have to go into stat and then select linreg(a+bx) for the straight line, but I'm not sure what to enter for that. For the curved line, you go into stat and then select expreg. If anyone remembers what to input next and how to understand the calculations please post a comment
2)how many roots does the function f(x)=3x4+4x3-x+0.05 have? what are they?
This function has a maximum number of four roots, because the polynomial has a degree 4. Also, since the degree is positive the graph of the function has its ends pointing upward. The minimum number of roots this function can have is zero.
3)f(x) = (7x2-3) * square root of(4-x2)
Here are my answers, we didn't get to go over these in class (post if i made an error)
iii)max @ y=67
iv)min @ y=9
Mr. Kuropatwa's lecture
Homework: rest your mind when you get home after school. Relax, have a bite, get some eye candy for about 30-45 minutes. Set a time for yourself when you can do homework after school and not too late. Make it a habit to do your homework at the same time for three weeks, this will train your body and make homework a breeze.
*not an accurate model*
Studies show that if you review your notes everyday, you will remember (up to) one-hundred percent of the material that was presented to you in class. IF you do not review your notes after the lecture and the days keep passing you by, you begin to forget. after nine days, the graph shows that you will only remember twenty-five percent of the material you learned!!!
Learning: it's easier to understand topics and materials given in class if you discuss about. Learning will be more fun and easier if you TALK. Ask questions in class, partake in the blog, listen attentively, attempt your HW, and talk to others in the class. This will help you practise and practise does make perfect.
Sisyphus was set up to fail for eternity, but he does not complain. He just keeps on going, even if he falls.
We are set up to succeed, and it is up to us to decide how far we want to take our success =)
Well, that was it for class. Sorry for posting a bit late. Also post help comments here for question 1 (at the top).
Its that time... i was going to pick someone who did not make a blogger account yet. Sounds kinda mean, but it is a good idea too. If i pick someone who didn't sign up they will sign up because they have to do the scribe =p.
HW: 1.1, odd numbers and question number four
OK...i am not picking someone who has not signed up yet. I choose the person whose name is next on the contributors list, the best Vice President (or i think Pres) Lindsay.
