math problem
@Florisalreadytaken
Do you remember what we did last time, first tell me,w hat's the vertex coordinate point
4, 1
Yes and we have \[a(x-h)^2 +k\] where (4,1) is (h,k) can you plug h and k in? what do you get?
a(x-4)^2+1
Yes so we have \[y=a(x-4)^2 +1\] We now have to solve for x tell me a random coordinate point on the parabola that isn't the vertex
2,3
!@snowflake0531
I htink you meant (3,2) \[2 = a(3-4)^2 +1\] solve for a
a(-1)^2+1
1+1
2 = 2
So, a=1
a = 2?
no a=1 1= a(-1)^2 1 = a(1) a=1 or something like that anyways a=1
So we have \[(x-4)^2 +1\] since we have to convert this to standard form, can you do (x-4)^2 remember that\[(a-b)^2 =a^2-2ab+b^2\]
\(\color{#0cbb34}{\text{Originally Posted by}}\) @snowflake0531 no a=1 1= a(-1)^2 1 = a(1) a=1 or something like that anyways a=1 \(\color{#0cbb34}{\text{End of Quote}}\) do you realise what you just wrote?
no
fair nuff
is she correct
positive
e.e i'm correct, i just said no bc floris was questioning me
so what is \[(x-4)^2+1\]
x^2-8x+17
yep so there's you ranswer
