Answer 2

?

Answer 3

A)

Answer 4

complete the square to solve the problem

Answer 5

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

Answer 6

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

Answer 7

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

Answer 8

A. y = x2 - 6x + 5

Answer 9

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.
