      Shadow Gaming my teacher stands in front of the board blocking me off from the lesson. I ask for her to move, but she just move 1 inch to the left, blocking me off completely. Then she gets mad when i don't understand her class.

    My algebra teacher played this but I barely got the information, here to rewatch. Mr. Allen if you’re seeing this I’m sorry I cried in class today. The work overwhelmed me and it just seems like everyone is too focused on their finished work to actually help others like me. I’m sorry I couldn’t process the information you tried helping me with too, but you didn’t let me do any of the work myself it was explained too fast. I’m sorry for crying afterwards too all the way to 4th period and during the open house. It’s hard. I feel stupid.

THANK YOU SOOO MUCH

  • @hensleysclass
    @hensleysclass  10 років тому +2

    Good question @Alasdair Vincent. You can choose whichever 'x' values you like, it's just easiest if you choose them to one side of the vertex, so that you can then mirror it on the other side. I chose the second number to be '0' because it's an easy number to plug in, and it's one unit to the right of the vertex, which would mean that I would plot it's symmetrical partner one unit to the left of the vertex. Then I chose '1' because, again, that's an easy number to plug into the equation. You can honestly choose 5 or -7 or 102 or whatever, but it will only make it more complicated.
    Another example would be as follows: If my vertex is at (3, -1)...what points would you plug in? In this case, I would choose '2' and then '1'...just because they are easier than '4' and '5'. Does this make sense? Hope it helps!

    for everyone that is struggling to find the vertex and axis, try completing the square; it is much quicker and have less margin for error. when equation is down to brackets; ex ( 2,-5) the vertex is 2,-5 and the axis of symmetry is always the first number so it is 2.. hard to explain without being able to use exponents. hope it helps
