Question 255127: A parabola forms the top of a fencing panel. This parabola can be modeled by the graph of the function y=0.03125x^2-0.25x+4 where x and y are measured in feet and y represents the number of feet the parabola is above the ground. How far above the ground is the lowest point of the parabola formed by the fence?
Do I start of the problem by using the formula
x= -b/2a ?
If so would it be
--0.25/2(0.03125) ?

Thank you very much for reading and reviewing my question. It is okay if you cannot answer it, I understand.
Thank you again so much really appreciate it.

=======================================
-b/2a is the x-coordinate.
Plug that into the equation to find the number of feet the parabola is
above the ground.

Believe it or not this equation factors out to be exactly.
y = 0.03125 (x^2-8x+128)
I believe you can start and end with the vertex formula. That is all it is asking about.
BTW You really should pay attention to your spell checker. Not doing so reflects badly on you.
I fixed most of your errors.
Attention to details is part of math.
