Answer:
Axis of Symmetry: x = 2
Vertex: (2, 3)
Explanation:
find axis of symmetry: x = -b/2a
x = -8 ÷ 2(-2)
x = 2
find vertex by substituting 2 for 'x':
y = -2(2²) + 8(2) - 5
y = -8 + 16 - 5
y = 8 - 5
y = 3
Vertex (2, 3)
You can look at the labeling from my last answer, the parabola is just upside down but it is still the same label.
Hope it makes sense :)
