Best ResponseYou've already chosen the best response.0Remember when you have f(x)=axh+k, the vertex is (h,k)

Best ResponseYou've already chosen the best response.0f(x)=axh+k f(x)=ax+39 What if i place them like this? Note that a=7/8 on the second one. Removed so they line up better

Best ResponseYou've already chosen the best response.0Look again and see which one goes with the h and which one goes with the k. They are lined up on top of each other

Best ResponseYou've already chosen the best response.0oh h is 3 and k is 9

Best ResponseYou've already chosen the best response.0Be careful with the h. Notice the sign change. You can solve it by equating whats inside the abs So, xh=x+3.

Best ResponseYou've already chosen the best response.0so its 3 and 9 and it's narrower and opens up?

Best ResponseYou've already chosen the best response.0It opens up but its not narrower. See a<1 where a=(7/8). So it's wider

Best ResponseYou've already chosen the best response.0oh okay. is my vertex right 3,9
