All change 11. Harold used the steps shown to correctly determine the coordinates of the maximum value of the given function by completing the square.
Given function: y=-
= -272-48-3
Step 1:
y = -2(+2x) - 3
Step 2:
2G?+ 2x +r) - 3+1
Step 3:
y = - 2(x+h)?+*
What are the values of randt in Step 2, and what are the coordinates of the maximum value of the function?
Or = 1, 1 = 2, and the coordinates of the maximum value are (-1,- 1).
Or=1, 1 = 2, and the coordinates of the maximum value are (1, - 1).
O r = 4,1 = 8. and the coordinates of the maximum value are (-2,5).
r = 4.1 = 8, and the coordinates of the maximum value are (2, 5).
