Question

Which of the following equations is of a parabola with a vertex at (1, 2)?

Answer 1

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

Answer 2

y = (x - 1) 2 - 2
is this the answer
