This parabola will be shaped like a 'U' because the a value (2) is positive. How to Use the Calculator 1 - Enter the x and y coordinates of three points A, B and C and press 'enter'.

Let’s say you have the following equation: y = 2x 2 -1.

Solution: The given equation can be rearranged as (y 2) 2 -4(x - 2) This represents a parabola with vertex V(2, 2) and opening towards the left because a -1 (negative). Example: Plot the parabola graph is given by the equation y 2 4y + 4x 4 0 and verify it using the parabola graph calculator.

X Expert Source Jake AdamsĪcademic Tutor & Test Prep Specialist Expert Interview. Solved Example on Parabola Graph Calculator. If you have trouble remembering this, think of it this way: an equation with a positive a value looks like a smile an equation with a negative a value looks like a frown.

If the a is negative, the parabola opens downward and has a vertex at its maximum point. If the coefficient a in the equation is positive, the parabola opens upward (in a vertically oriented parabola), like the letter 'U', and its vertex is a minimum point.It can also be written in the even more general form y = a(x – h)² + k, but we will focus here on the first form of the equation. The general equation of a parabola is y = ax 2+ bx + c. James 1.26K subscribers If you know the zeros of a quadratic function, then you have. The Arc Length of a Parabola calculator computes the arc length of a parabola based on the distance (a) from the apex of the parabola along the axis to a point, and the width (b) of the parabola at that point perpendicular to the axis. If it opens downward or to the left, the vertex is a maximum point. Determine the Equation of a Parabola given zeros and a point 26,611 views 192 Dislike Share Save Mr. If the parabola opens upward or to the right, the vertex is a minimum point of the curve. The point where the axis of symmetry crosses the parabola is called the vertex of the parabola. Question 403685: find the equation of a parabola given 2 points on the parabola, (5,9)&(1,9), and the directrix d:y-1. This is a straight line that passes through the turning point ('vertex') of the parabola and is equidistant from corresponding points on the two arms of the parabola. The parabola is the locus (series) of points in which any given point is of equal distance from the focus and the directrix. A fixed point on the interior of the parabola that is used for the formal definition of the curve. Here are the parts of the parabola that you'll need to know: X Research source You may be given certain information prior to beginning, and knowing the terminology will help you avoid any unnecessary steps.
