Best ResponseYou've already chosen the best response.0The graph of which quadratic equation has a vertex of (2,1). Y=(x+1)^22 Y=(x1)^22 Y=(x+2)^2+1 Y=(x2)^2+1

Best ResponseYou've already chosen the best response.0need it by hand (for question 1), then I would suggest matrix. it is already in order for a matrix.

Best ResponseYou've already chosen the best response.0now, where would this (h,k) be (2,1) ? In which of the options?

Best ResponseYou've already chosen the best response.0y=(xh)²+k you need vertex (2,1) and in that form the vertex is (h,k) so h=2, k=1 y=(x (2) )² + (1) y= ? (you tell me....)

Best ResponseYou've already chosen the best response.4where did your \(1\) come from? \[y=(x\color{blue}h)^2+\color{red}k\] put \[\color{blue}h=\color{blue}{2}\] and \[\color{red}k=\color{red}1\]

Best ResponseYou've already chosen the best response.4\[y=(x(2))^2+1\] but of course you don't want to write \((2)\)

Best ResponseYou've already chosen the best response.4yeah that one has vertex \((2,1)\)
