Quadratic Equation Vertex Form Math
The only trick there is to remember that his the opposite sign of what is written.
Quadratic equation vertex form math. The h represents the horizontal shift and k represents the vertical shift. The vertex of a quadratic equation can be read from vertex form it is h k. Given a quadratic function. Y a x h 2 k is the vertex form equation.
Ax2 bx c x b 2a finding the x coordinate of the vertex. The vertex form of a quadratic equation is. The y intercept is still found by replacing xwith zero and simplifying. Multiply by the coefficient of a and get y ax 2 2ahx ah 2 k.
You should get y a x 2 2hx h 2 k. Where a is a constant that tells us whether the parabola opens upwards or downwards and h k is the location of the vertex of the parabola. Hence color blue vertex 3 8. The following vertex formula will give us the x coordinate for the vertex of the parabola.
So for y 3 x 1 2 2 the vertex is 1 2. A x h 2 k. Quadratic equations in vertex form have a general form. Direct link to alex tran s post y a x h 2 k is the vertex form equation.
The vertex form of a quadratic function is given by f x a x h 2 k where h k is the vertex of the parabola. Now expand the square and simplify. The standard form of a quadratic equation is ax 2 bx c. Vertex form is another form of a quadratic equation.
