okay guys so these ones are for you guys to do number 7 is already put in factored form for you guys so you don't need to factor in and the number 8 you do have to factor so go ahead and pause it and work with someone next to you and go ahead and grab these two for me please and the next thing you guys are going to see is the answers  before I show you guys the answers I recognized I miss gave you the graph for number 7 so I just shipped in my line over a little bit that way I had enough space to graphic you guys might want to do the same say now I will give you the answers  playoffs for the other ones and then I realize that I should have enough time to switch the graph on your paper so nor that your grass should be right but here any answers so you should get for your vortex the first one don't know this is wrong x equals play Vybz equals 2.5 and then -2.25 X  my goodness I can't speak anymore okay are vertex is 2.5, -2.25 and then your exit and intercepts are one for for number 8 your X intercepts are negative through 43 oh my goodness my words are just I'm sorry exit you can see it and then my vertex is -.5, native 12.25 alright so then let's do our next set of problems he's or more practice problems like the last one we just did the really long one but no mine is actually much simpler I'll do 9 and 10 but 11 will be for you guys to try on your own so number 9 says x-intercepts so anytime Rec Center sets were just going to put them in your parentheses and what if we notice that happens every single time we have are X intercepts so like for example for this and right here x + 4 but then our answer was opposite signs right so when we plug it in there going to have office sign so it's going to be ax + 1 +  x minus one  = f or why whichever you want umbrakinesis put it in standard form so that means I actually have to multiply it out so f of x equals x x x x squared x x native one is negative x 1 x x is positive 1 x + 1 * -1 is -1 what do we know happens with our  middle terms they cancel out so our final answer f of x equals x squared minus one that's it  let's see if I can make it through this next one this Play Along video if I do that actually no I'm going to just do my doodoo video when you're ready video
