    first of all the parabola definitely opens up indicated by x^2

    because it is positive x^2 whereas if it was -x^2 then you would know it is an upside down parabola or opens down.

    ok, to find the vertex(turning point) simply we need to factorize the equation first.

    vertex is definitely a minimum because the graph is opening upwards.

    it's opening upwards so there's a minimum.

    opposite applies so opening downwards, there is a maximum
