Question

rewrite f(x) = x2 − 8x + 3 in vertex form.

Answer 1

vertex form f(x) = a(x-h)^2 + k
h = -b/(2a)

Answer 2

standard f(x) = ax^2 + bx + c

Answer 3

Vertex form is y = a(x - h)^2+ k, when H is X in ordered pair and K is Y in ordered pair. To solve this, we can solve by completing the square.
y-3=x2-8x,
y-3=(x-4)^2
y-3+16=(x-4)^2
y+13=(x-4)^2
[ y=(x-4)^2-13 ] <-- The vertex form
