Andy completes the square for the function y = x^2 + 6x -8 Which of the following functions reveals the vertex of the parabola?
LiRa [457]

Answer:

B. y = (x + 3)^2 - 17

Step-by-step explanation:

... y = x² +6x +9 -8 -9

... y = (x² +6x +9) -17

... y = (x +3)² -17 . . . . . . . . matches selection B
