In a standard form, the vertex is f(x) = (x -1)² + 1.
The vertex of a quadratic equation in standard form.
The vertex of a quadratic equation in standard form can be expressed as f(x) = a(x - h)² + k. Here, the vertex of the parabola is (h,k).
To express the vertex of the quadratic equation in standard form, we need to be able to write the quadratic equation of the parabola curve,
The parabola pass through the points on the graph; (0,0) (1,-1) and (2,0). Thus, the equation for the parabola in standard form can be expressed as:
f(x) = x² - 2x
The vertex is form of (h,k) is = (1,-1)
In a standard vertex form: f(x) = a(x - h)² + k
f(x) = 1(x - 1)² + 1
f(x) = (x -1)² + 1
