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

actually knowing that the graph is just shifted down 25 units the midpoint should be 0,-25 i think

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