Answer:
Explain to me how you expect anyone to do this,
as you haven't provided the graph or the inequalities.
Step-by-step explanation:
The height is represented as y and the time is represented as x.
To find the maximum height (since this is a parabola that faces downwards) we need to find the vertex.
Vertex (x) =

b = 14
a = -16
Substitute

Now plug 7/8 to t
-16(7/8)^2 + 14(7/8)
-16(49/64) + 14(7/8)
-12.25 + 12.25
