How Parabola Graph Calculator Works?

Parabola is obtained by slicing a cone parallel to the edge of the cone. It is of U – shape as a stretched geometric plane. The general form of the parabola is given by y² = 4ax

The general equation of a parabola is given by:

y = a(x - h)² + k (regular)

x = a(y - k)² + h (sideways)

Where (h, k) is the vertex of the parabola and a is the perpendicular distance from the focus to a point on the curve.

Let us understand this with the help of the following example.

Solved Example on Parabola Graph Calculator

Example:

Plot the parabola graph is given by the equation y² − 4y + 4x − 4 = 0 and verify it using the parabola graph calculator?

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).

The focus will lie at a distance of 1 unit to the left of (2, 2), i.e., at (1, 2)

The directrix will lie 1 unit to the right of (2, 2), i.e. it will be x = 3

Similarly, you can use the parabola graph calculator and compute for:

• y² = 15x
• (y + 8)² = -8(x + 5)
• y² - 10y + 6x + 9 = 0
