Help Please!!!
How do the parameters a,h,k in the general equation 
y=a(x-h)^2+k affect the graph of a quadratic function?

anonymous · Answer

i was trying so hard but lets face it I AM NO HELP!!!! hope you get ur answer

mathmale · Answer

y=a(x-h)^2 + k is the equation of a parabola (a quadratic function).

Think:  What does ' k ' represent?  what would happen to the graph of the parabola were you to increase k by 2?

izzy18970 · Answer

The graph would move up or down

mathmale · Answer

Partially right.  Would it move up?  Would it move down?  Which?

izzy18970 · Answer

If it increases by 2 then it would move up

izzy18970 · Answer

I believe with h if it is positive it moves rights and if its negative it moves left. With A it would affect the parabola by opening upward or downward. And if A is less than 1 the parabola becomes wider, if it is greater than 1 it becomes steep

How can I explain this simplified? If I'm correct

@mathmale are you there?

Go here https://www.desmos.com/calculator type in y = A*(x-H)^2 + K ad slider bars to let you change A,H,K, and observe the effects..
