A rectangle is inscribed with its base on the x-axis and its upper corners on the parabola y=8-x2 . What are the dimensions of such a rectangle with the greatest possible area? width=? height=...

I found three points of my parabola: (2.5, 1), (7, 4), and (11.5, 1). I need to put my parabola into standard form, but I am not sure how to do it with the information that I have.

Find the focus, directrix, and focal diameter of the parabola. 2xsqaured +13y = 0

Given the equation -5 (x - 2)2 -1=y a. Identify the vertex. b. Identify the axis of the symmetry. c. Identify the direction of the graph (whether it opens up or down).

How can I find the equation of a parabola when I am given a=1 (I have a graph but do not know the steps I need to take)

I had to find the coordinates of the vertex and the equation of the axis of symmetry for the parabola given the by the equation h(x)=-1/2x to the 2nd power +4x-8 and the answer I came up with...

Two parabolas y=16-3x2 and y=x2-9 are drawn. A rectangle is contructed with sides parallel to the coordinate axes with the two upper vertices on the graph of y=16-3x2 and the two lower vertices...

The equation of parabola is y=_________

this is for my math assighnment that is overdue

conic sections - parabolas, ellipses and hyperbolas.  Look around in your day (home, work, etc) and see if you observe any of the conic sections.  In each explanation, indiciate what...

Sometimes only half of a parabola is used to model data. Why is this the case? Why would we not be interested in both sides?

So, I was playing with an online graphing calculator and I plugged in 0.5x2 x2 and 2x2 and when I went up to higher numbers, such as x=10, I noticed they were unevenly spaced. This...

using y = x^2 - 4x -32 how do I identify if the parabola opens up or down so I can explain the conclusion.     Thank you
