to find vertex use -b/2a to find axis of symetry take the x value from the vertex Domain should be easy its a parabola shifted down 25 units and the range is All known numbers
OpenStudy (sweetburger):
actually knowing that the graph is just shifted down 25 units the midpoint should be 0,-25 i think

Yes, however when i choose my answer it said it was wrong, Ill show you what i did

no you must notice that a would be represent by x^2 remember the notation ax^2+bx+c
OpenStudy (sweetburger):
also there is no b value for this equation
OpenStudy (sweetburger):
so -(0)/2a=0 which is your x value and axis of symetry

Oh, I see Thank you
