It's been a while since I was in high school so can I ask what standard form is (for question 2)?
9th grade here! I need help with a problem.. this is it:
Write y=a(x-h)^2+k and y=a(x-p)(x-q) in standard form. Knowing the
vertex of the graph of y=ax^2 + bx +c occurs at x=-b/2a, show that the vertex of the
graph of y=a(x-h)^2+k occurs at x=h and that the vertex of the graph of y=a(x-p)(x-q)
occurs at x=p+q/2.
This is how far I got:
a=a b=-2ah c=ah^2+k
I'm stuck here, how to I arrange it to be standard form?
Your work seems to be correct,
. . but I'm not sure where (or why) you are stuck.
I'll walk through it for you.
(a) Write and in standard form.
(b) Knowing the vertex of the graph of occurs at
show that the vertex of the graph of occurs at
and that the vertex of the graph of occurs at
