Answer:
- relationship: inverse
- equation: y = 25/x
Step-by-step explanation:
You are correct that the relationship is inverse, and that the product of x and y is a constant, 25.

The x in the denominator clearly shows that y is proportional to the inverse of x.
Answer:
Opening: Opens upwards
Axis of Symmetry: -7/2
Vertex: (-7/2, -81/4)
X - intercepts: (1, 0) and (-8, 0)
Y - intercept: (0, -8)
Step-by-step explanation:
Opening: 'a' is greater than zero
Axis of Symmetry:
Vertex:
X - intercepts:
(x-1)(x+8)
x = 1 and x = -8
Y - intercept: (0, -8)
