where do you need help?

anonymous · Answer

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

anonymous · Answer

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.

anonymous · Answer

I need helping showing work for vertex and x intercept

anonymous · Answer

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

anonymous · Answer

do you know how to do that?

anonymous · Answer

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

anonymous · Answer

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