Best ResponseYou've already chosen the best response.0idk..its something to do with ellipses, parabola, or hyperbola...that what the section was about

Best ResponseYou've already chosen the best response.0i can help with the parabola, not sure about that line though

Best ResponseYou've already chosen the best response.2What is the vertex? You need both them to write out the equation. Please, answer.

Best ResponseYou've already chosen the best response.2The red line below to the graph is a directrix

Best ResponseYou've already chosen the best response.2if you don't know that method, ok, pick 3 points on the graph. Please.

Best ResponseYou've already chosen the best response.2Now, what method do you want me to follow?? directrix method or standard one?

Best ResponseYou've already chosen the best response.0which one do u think would be the easiest to understand?

Best ResponseYou've already chosen the best response.2Depend on you. I am ok with both

Best ResponseYou've already chosen the best response.2what is the standard form of a parabola?

Loser66

Best ResponseYou've already chosen the best response.2now, 3 points Vertex (1,4) you pick other two.

Best ResponseYou've already chosen the best response.0just 2 random points?

Loser66

Best ResponseYou've already chosen the best response.2Yes, but for convenience, you should pick the point whose coordinates are integers like (1,5). Got what I meant?

Best ResponseYou've already chosen the best response.0so the points where the red line cross over?

Loser66

Best ResponseYou've already chosen the best response.2no, the point on the parabola

Best ResponseYou've already chosen the best response.2Now, starting Vertex \((\color{red}{1}, \color{blue}{4})\) Plug them into the standard form like \(\color{blue}{4}= a\color{red}{1^2}+b\color{red}{1}+c\) you have 4 = a +b +c, right? name it as (*) Do the same with other two point, what do you get?

Best ResponseYou've already chosen the best response.0@Loser66 am I understanding it?

Best ResponseYou've already chosen the best response.25=a b +c, yes but for (3,5) it is not right 5 = a(3^2) +b(3) +c , that is 5= 9a +3b+c

Loser66

Best ResponseYou've already chosen the best response.2Now, you have 3 equations, 3 unknowns a, b, c. You can solve for them a + b + c = 4 (*) a  b + c = 5 (**) 9a + 3b + c = 5 (***)

Loser66

Best ResponseYou've already chosen the best response.2Take (*) (**) , what do you get?

anonymous

Best ResponseYou've already chosen the best response.0so i have 1 left, and 9a + 3b + c = 5

Loser66

Best ResponseYou've already chosen the best response.2Replace a = 1/4, b = 1/2 in (*) you get c = ??

Loser66

Best ResponseYou've already chosen the best response.2yes, or 17/4 Now, plug back to standard form, y = ax^2 +bx+c . that is your answer.

Loser66

Best ResponseYou've already chosen the best response.2a = 1/4 b= 1/2 c = 17/4 Plug in \(y= ax^2+bx +c\)

Best ResponseYou've already chosen the best response.0there might be a somewhat easier way to get this, using two points although above method certainly works
