Hello, sorry for the delay.
On Friday, we corrected a few questions based on Exercise 2: Graphs of Quadratic Functions 1, questions number 11 and 12.

11.)
x = cost of an ice cream cone
J (x - 24)
K (x - 2)

(x- 24) + (x - 2) < x
2x - 26 < x
x - 26 < 0

24 < x < 26
x = 25

12.)










x = 751m


cos(55) = x / 751

cos(55)*751 = x

430.75m = x


* Another thing we did was make a table.

ex. y = x2 : its vertex, Domain, Range
and the Axis of Symmetry












* y = a (x - h) 2
* 2 means squared

vertex ( h , 0 )



Again, I'm so sorry for the late post. I left class a little early, but I heard that we have to do Exercise 3, question 1. Next scribe is Dylan.
