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
