What attribute(s) of the graph of a parabola can you immediately find given the factored form of a quadratic function? What attribute(s) of the graph of a parabola can you immediately find given the vertex form of a quadratic function?

Answer:

The factored form of a quadratic equation is

[tex]y=a(x-m)(x-n)[/tex]

Where [tex]m[/tex] and [tex]n[/tex] are real numbers.

Though this form, we can deduct the parabola direction, if it opens upside or downside. Additionally, we can also deduct the x-axis interceptions, which in this case are [tex]x=m[/tex] and [tex]x=n[/tex], they are also called the roots of the equation.

The vertex form of a quadratic equation is

[tex]y=a(x-h)^{2} +k[/tex]

Using this form we can deduct the parabola direction, if opens up or down. Also, we can deduct the vertex of the parabola, which has coordinates [tex](h,k)[/tex], parameters of the vertex form.

Therefore, as you can observe, the different forms of a quadratic equation can give us different information.
