The equation of the parabola is the simplest when the vertex of a parabola is at the ‘origin’ and the axis of symmetry is along the x ory-axis. Let us derive the equation of a parabola in itsstandard form. Let S be the focus and Z, Z’ be the directrix of a parabola. Raw SK...
Find the standard form of the equation of the parabola with the given characteristic(s) and vertex at the origin. Focus: (0, - 2) Find the standard form of the equation of the parabola with the given characteristic(s) and vertex at the origin. Focus...
State the vertex, directrix, and intercepts of the parabola having the equation (x + 3)2 = −20(y − 1).The temptation is to say that the vertex is at (3, 1), but that would be wrong. The conics form of the equation has subtraction inside the parentheses, so the (x + 3)...
Standard equation of a parabola y=ax2+bx+c Answer and Explanation:1 Given: The vertex of the parabola is(−2,5), and curve passes through the point(0,9). By the geometry of points, we can... Learn more about this topic:

{/eq} is a shape called aparabola. The graph of any quadratic equation shapes like a parabola. The point where the parabola "flips over" is called thevertexof the parabola, and the vertex of the graph of {eq}y = x^2 {/eq} is located at the origin (that is, the point (0,0)...
parabola vertex y=x2 Recall that the standard form of a quadratic equation isy=ax2+bx+c. This graph will always be a parabola, but it will move around based upon the values ofa, b,andc.Here are some general pointers: Ifais positive, the parabola opens upward. Ifais negative, the par...
