How do you find the equation of a parabola given two points without a vertex?
How do i find the equation of a parabola given 2 points and the axis of symmetry, but no vertex?
- Using the vertex form of a parabola f(x) = a(x – h)2 + k where (h,k) is the vertex of the parabola.
- The axis of symmetry is x = 0 so h also equals 0.
- a = 1.
- Substituting the a value into the first equation of the linear system:

How do you find a quadratic equation?
The value of discriminant (b2 – 4ac) determines whether the graph of a quadratic equation will:
- Intersect the x-axis at two points i.e. b2 – 4ac > 0.
- Just touches the x-axis i.e. b2 – 4ac = 0.
- Never intersects the x-axis i.e. b2 – 4ac < 0.
