Answer 3

@jdoe0001

Answer 4

\(\large {\begin{array}{llll}
(y-{\color{blue}{ k}})^2=4p(x-{\color{brown}{ h}}) \\
(x-{\color{brown}{ h}})^2=4p(y-{\color{blue}{ k}})\\
y=(x-{\color{brown}{ h}})^2+{\color{blue}{ k}}\\
x=(y-{\color{blue}{ k}})^2+{\color{brown}{ h}}
\end{array}
\qquad
\begin{array}{llll}
vertex\ ({\color{brown}{ h}},{\color{blue}{ k}})\\
\end{array}
}\)

Answer 5

this confuses me

Answer 6

pick any of the vertex quadratic forms

Answer 7

hmm? you;'re given the vertex coordinates already, so just plug and chug :)

Answer 8

wait i think i got it

Answer 9

i got (x-4)^2-15

Answer 10

yeap that'd be a quadratic with a vertex at (4, -15)
