how do you find the minimum of a parabola that has the x- intercepts -2 and 4 and goes through the point (3,-15)?
I don't get how to get the minimum if I don't have a starting equation to work with can someone please help me on this ?

That's what I was wondering if u could help me get the equation I don't get what I have to do next ?
I know how to solve that equation x= 1 and y =2
I was wondering if you could help me understand how to get the minimum parabola with out having a equation to start with ?
I know about a parabola but only when I have an equation then I can find the maximum or minimum but with out and equation it's hard to find that or I just don't understand how to find that .

Okay so far I get it.
what I don't get is what do I do with the z because by substituting I got :
4a-2b+z=0
16a+4b+z=0
9a+3b+z=-15
