Vertical Parabola Formula
The formula for a vertical parabola is generally given by the equation:
y = a(x – h)^2 + k
In this equation:
– “a” represents the coefficient that determines the shape and direction of the parabola
The formula for a vertical parabola is generally given by the equation:
y = a(x – h)^2 + k
In this equation:
– “a” represents the coefficient that determines the shape and direction of the parabola.
– (h, k) represents the vertex point, which is the lowest or highest point on the parabola (also known as the minimum or maximum point).
– (x, y) represents any point on the parabola.
If the coefficient “a” is positive, the parabola opens upwards, with the vertex being the minimum point.
If the coefficient “a” is negative, the parabola opens downwards, with the vertex being the maximum point.
To determine the coordinates of the vertex (h, k), you can use the following formulas:
– h = -b/2a
– k = f(h), where f(h) represents the value of y when x = h.
The axis of symmetry, i.e., the vertical line that passes through the vertex, is represented by the equation:
x = h
Additionally, the x-intercepts of the parabola (also known as the roots or zeros) can be found by setting y = 0 and solving for x. This can be done by factoring, completing the square, or using the quadratic formula, depending on the form of the equation.
It’s important to note that the formula given above represents a simplified form of the equation for a vertical parabola. If the equation is given in a different form, such as standard form (ax^2 + bx + c = 0) or vertex form (y = a(x – h)^2 + k), it may require some algebraic manipulations to rewrite it in the form mentioned earlier.
