Best ResponseYou've already chosen the best response.1usually, to check which value is the xcoordinate of the vertex, just check what value of x will make the bracket zero. in this case it's (4 + 4)^2  33 so xcoordinate = 4

Best ResponseYou've already chosen the best response.1oh, sorry, I never saw the equation was x = y^2 + 8y  17 it's gonna be a bit different now, I'll post the solution now

Best ResponseYou've already chosen the best response.1the vertex is at (h, k) and the general form is y=(x h )^2 + k but since the parabola x = y^2 + 8y  17 dw:1354919627767:dw

Best ResponseYou've already chosen the best response.1no the parabola is concave right.... its x = y^2 + 8x  17

Best ResponseYou've already chosen the best response.1I've seen your method.... but the parabola is not the traditional concave up parabola...

Best ResponseYou've already chosen the best response.0so it would be (4,33) ?

Best ResponseYou've already chosen the best response.0yes, @slaaibak but its (h,k) so (4,33) right?

Best ResponseYou've already chosen the best response.1the methodolgy is correct... here is the graph attached the error is in the general form that you have used. for parabola that are in the form x = ay^2 + by + c the vertex form is x = (y  k)^2 + h
