in class, my partner and i had a slow computer and couldnt even start the hw... on #4 in 4.1a... i dont have a "graphing window" on the page of the computer. what do i do?
Hi Meg - As we discussed in class, this is a newer version of the graphing calculator than when I created the Lab 4.1 packet. In order to see the graphing window, you have to click on the "Set Window" button. My suggestion for beginners is to set the Auto-Scale checkbox "off" so that you can control the graphing window settings. Play with it a little bit and you should get the idea of how it works.
To ALL: Feel free to ask more questions... and play with the function machine on MathChamber Unit4!
I want everyone to be COMFORTABLE with the graphing calculator... it is something that will help you with mathematics throughout high school AND college!
For 9 & 10, a SOLUTION is a pair of numbers, x&y, or (x, y) that "satisfy" the equation. In other words, a pair of numbers that make the equation TRUE.
When equations are in 'y=' form, it is generally easy to "plug in" arbitrary (randomly selected) values for x to generate a "satisfactory" y value.
For example, for #9, if x = 3 then 2x-4 = 2(3)-4=6-4 which finally = 2. So, you can say when x=3 then y=2. So, ONE SOLUTION to this equation is the ordered pair (3, 2). You tell me, what will be the value for y when x=5? Whatever value you get will generate another SOLUTION to the equation, e.g. (5,?).
For 13 & 14, come to class on Thursday, read Ms Engelfried's packet and BE READY TO LEARN!!!

I get the function of x thing now Mr C!
ReplyDeleteI'm glad... maybe now you can teach me!
ReplyDeleteFor lab 4.1B, are we supposed to make a graph like the one on the graphing calculator? Except on graph paper?
ReplyDeleteI would like you to graph the functions on graph paper first, and then check your work using the graphing calculator, ca-peesh?

i didnt get 13 or 14 or 9 or 10
ReplyDeleteWhat quadrant is a number in if it is on an axis?
ReplyDeletesee the post for hw #4-3 for the answer
ReplyDeleteFor the question about 9-10,13-14
