If you have any questions, leave a comment here.

Will you be in your class room at the start of lunch tomorrow?
ReplyDeleteOn Monday the sub said that the brackets were in the wrong places when you taught us on Friday and in the note as well. Then in the homework it showed examples of doing it with the numbers inside of the brackets.
ReplyDeleteShould we do it her way with the numbers in the brackets on the test?
1. Why was the second part of question 4 neccessary? Why couldn't you just find out what "a" was and then put that into the equation?
ReplyDelete2. Wil the value of q always be the y intercept?
3. For question 10, how could we tell that it had been translated at all? What if there were no brackets?
4. How would we know not to use the information in question 11 about the speed being 25 m/s? We didn't include that once in our equation? is it just there to screw us up?
Whoever Anonymous is, yes I'll be in my room tomorrow.
ReplyDeleteJen, do it the way I taught you, it is easier.
Rachel,
Question 1)
The second part of the question isn't necessary so long as you are capable of putting the values of the vertex in the correct place. I just did it the long way so you could see what was happening.
Question 2) Answer, Yes
Question 3) The values inside the brackets reference "p". Remember "p" is the value of the x coordinate of the vertex, so in this case the vertex is translated 3 units to the right, not the left as Stan says. If there are no brackets then there is no "p" so the vertex is on the y axis.
Question 4) Just there to mess you up. The 25m/s has no bearing other than to describe to you how fast the ball is thrown. IF the question is given to you, go with it.
