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...
focus at (0,2)
Find the point on the graph of y=x2 +1 that is closest to the point (8, 3/2).
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
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?

parabolas, ellipses and hyperbolas can someone give me three conic sections.indiciate mathematical features of the conic corresponds within the examples.
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...
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
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...
f(x)=x^2-4x-5 The vertex of the given parabola is _____. (typed an ordered pair)
I am trying to make a mold for satellite dish . I can calculate the maths but my biggest challenge is plotting the graph . I need a tutor that can put me through
Graph the parabola
answer for math questions about parabolas
How do I solve the equation: -4 = -1 divided by 4*a
I also need the the equation in standard vertex form and the axis of symmetry and the direction of opening
write an equation of the parabola that models the cross section of the mirror. Assume that the parabola opens upward. Find the vertex, focus, and the directrix
A mirror with a parabolic cross section is used to collect sunlight on a pipe located at the focus of the mirror. The pipe is located 5 inches from the vertex of the mirror
Two satellites are orbiting earth. The path of one has the equation x^2 +y^2 = 2250000. The orbit of the other is 200 km farther from the center of earth. In one orbit, how much farther does the...
i dont understand which way it would open! /;
