Answer 2

ok
so

Answer 3

yeaa

Answer 4

(6-2)/2=4/2=2 => 2+2=4 => vertex is (5,4)
b will be the distance between the vertex and the directrix or focus.

(x−h)^2=4b(y−k) ((h,k) is vertex )
b=2
(h,k)=(5,4)
Plug and get this equation: (x−5)^2=8(y−4)

now simplify this equation and find your answer

Answer 5

simplifying is easy

Answer 6

−one eighth (x − 5)2 + 4?

Answer 7

wait one eighth (x − 5)2 + 4

Answer 8

yeah 1/8*(x-5)^2+4=y

Answer 9

okk thx!
