complete the square to solve the problem

anonymous · Answer

Yes the answer is A if you click the link it will show you the same graph

anonymous · Answer

(x-1)*(x-5)=x^2-6x+5

anonymous · Answer

A because when you solve for x=3, it gives y=-4, just like in the graph

anonymous · Answer

A.	y = x2 - 6x + 5

turingtest · Answer

Look at answer A)$$y = x^2 - 6x + 5$$completing the square means we will add 9 to both sides$$y+9=x^2-6x+9+5$$$$y+4=(x-3)^2$$which if you know the formula for a parabola, you realize points up and has a vertex$$(3,-4)$$so that is the correct answer.
