**Everything You (N)ever Wanted to Know About Parabolas**

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... 3/05/2011Â Â· Best Answer: Knowing whether an equation is a conic section (circle, ellipse, hyperbola, parabola) or a line lies on algebraic manipulation; that is, in how you rearrange stuff in the equation. In determining what figure an equation represents, you have to rearrange it until you end up with an equation â€¦

**Finding the Equation of a Parabola Given Focus and Directrix**

If the equation has an x^2 term but NO y^2 term, or a y^2 term but NO x^2 term, then it probably a PARABOLA. I say "probably", because there under certain other conditions, there may be exceptions in which the graph is a point or no solution.... Sal manipulates the equation x^2+y^2-3x+4y=4 in order to find that it represents a circle, and the equation 2x^2+y+12x+16=0 in order to find it represents a parabola.

**How can i know that an equation is of a parabola circle**

If the equation has an x^2 term but NO y^2 term, or a y^2 term but NO x^2 term, then it probably a PARABOLA. I say "probably", because there under certain other conditions, there may be exceptions in which the graph is a point or no solution.... 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.

**How Can Parabola to Have no x Intercepts? Math**

State the vertex and focus of the parabola having the equation (y â€“ 3) 2 = 8(x â€“ 5). Comparing this equation with the conics form, and remembering that the h always goes with the x and the k always goes with the y , I can see that the center is at ( h , k ) = (5, 3) .... 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€¦

### Parabola, Horizontal Translation. Back Function Institute Mathematics Contents Index Home. Horizontal translation for the parabola is changed by the value of a variable, h, that is subtracted from x before the squaring operation.

- Standard Forms of a Parabola. Alex Szatkowski. In this exploration, I will investigate the relationship between the two standard forms of the graph of a parabola. and . What I know about - "a" affects the shape (wide, or narrow)
- A quadratic function through three points Another application of quadratic functions is to curve fitting, also called the theory of splines. Since a parabola is specified by three numbers, it is reasonable to suppose that we could fit a parabola to three points in the plane.
- 21/05/2008Â Â· The problem statement, all variables and given/known data when asked to identify an equation as a parabola, hyperbolas, ellipses, circles, straight lines, or none of the above, how can i deduce which is which? the problems given are: 2x^2+2y^2=9 (im pretty sure this one's a circle,...
- A parabola is a section of a right circular cone formed by cutting the cone by a plane parallel to the slant or the generator of the cone. It is the locus of a point which moves in a plane such that its distance from a fixed point is the same as its distance from a fixed line not containing the fixed point. The equation of any conic section can
