For y = x2 − 4x + 3, Determine if the parabola opens up or down. State if the vertex will be a maximum or minimum. Find the vertex. Find the x-intercepts. Describe the graph of the equation. PLEASE HELP! Need to finish this..

    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.

    And if the vertex is max or min. And no I do not.

    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
