**Identifying equations as parabola hyperbolas ellipses**

for = the parabola with equation = and; for > a hyperbola (see picture). In polar coordinates. Pencil of conics with a common focus. If p > 0, the parabola with equation = (opening to the right) has the... 25/07/2009Â Â· The standard form for the vertex of the parabola (at least in the eyes of a student first being exposed to these equations) looks complicated and just like another bit of random jiberish to remember. I personally prefer understanding the concepts and applying it through logic, rather than following some general form equation.

**Conic section from expanded equation circle & parabola**

16/04/2013Â Â· It will be important to determine if our transverse axis is horizontal or vertical as the equation for the two will be different. In addition to an ellipse and parabola a hyperbola has two... 24/04/2008Â Â· I know if the equation is y=ax^2 it opens up or down, and if a<0 it opens down and if a>0 it opens up, but... I know if the equation is x=ay^2 it opens left or right, but I don't know how to tell which one... thanks for the help!!!

**How to Identify the Min and Max on Vertical Parabolas**

We place the vertex of the parabola at the origin (for convenience) and use the equation of the parabola to get the focal distance (p) and hence the required point. In general, the equation for a parabola â€¦... After watching this video lesson, you will be able to write the equation of a parabola in standard form when given just two important points from the parabola.

**How can you tell if an equation is a parabola?**

In the first equation, you see an x 2 but no y 2, and in the second equation, you see a y 2 but no x 2. Nothing else matters â€” signs and coefficients change the physical appearance of the parabola (which way it opens or how fat it is) but donâ€™t change the fact that itâ€™s a parabola.... 6/01/2009Â Â· Best Answer: Hi, If xÂ² and yÂ² both have the same coefficients like xÂ² + yÂ² or 3xÂ² + 3yÂ², then it is a circle. If xÂ² and yÂ² both have different coefficients that have the same sign, like 4xÂ² + 9yÂ², or xÂ² + 16yÂ², then it is an ellipse.

## How To Know If Equation Is Parabola

### for = the parabola with equation = and; for > a hyperbola (see picture). In polar coordinates. Pencil of conics with a common focus. If p > 0, the parabola with equation = (opening to the right) has the

- Did you want to know if 2 points lie on a particular parabola? If so, it is just a matter of finding out if one point lies on the parabola and repeat for the second point. How do you do that? Assuming you have a quadratic equation along the lines of y-ax^2+bx+c, just plug in the x value and see if the value of y matches your point.
- This means that if we know a point on one side of the parabola we will also know a point on the other side based on the axis of symmetry. We will see how to find this point once we get into some examples.

- The lesser the quadratic coefficient, the wider the parabola. In this graph, coefficient a is positive and large. Therefore the parabola is narrow and points upward.
