A parabola is a U-shaped curve that features in the branch of mathematics called algebraic geometry. It is one of the most widely studied curves and has many applications in fields such as physics, engineering, and computer graphics.
The general equation for a parabola is given by:
y = ax^2 + bx + c
where ‘a’, ‘b’, and ‘c’ are constants. The parabola can open upward or downward depending on the value of ‘a’. If ‘a’ is positive, the parabola opens upward, and if ‘a’ is negative, the parabola opens downward.
The vertex of the parabola is the point where it reaches its minimum or maximum value. The x-coordinate of the vertex can be found using the formula:
x = -b / (2a)
The y-coordinate of the vertex can be obtained by substituting the x-coordinate into the equation.
The axis of symmetry is a vertical line that passes through the vertex and divides the parabola into two symmetric halves. The equation of the axis of symmetry is given by:
x = -b / (2a)
The y-intercept of a parabola is the point at which it intersects the y-axis. To find the y-intercept, substitute x = 0 into the equation of the parabola and solve for y.
To graph a parabola, it’s helpful to identify the vertex, axis of symmetry, and y-intercept. Additionally, you can find more points on the parabola by choosing different x-values and calculating the corresponding y-values using the equation of the parabola.
