Answer:
(2, 17)
Step-by-step explanation:
observe
y = –2x² + 8x – 8 + 17
y = –2(x² – 4x + 4) + 17
y = –2(x–2)² + 17
so, the vertex is (2, 17)
Answer: (2, 17)
Step-by-step explanation:
The parabola params are: a = -2, b = 8, and c = 9
xv = -8/2(-2)
so xv = 2
yv = -2 times 2^2+8 times 2+9
therefore yv = 17
