HELP Sam was asked to write the equation of a
parabola in class. He was given the
following information:
Focus: (5, 1) Directrix: y = -5
Opens upward
E
Sam wrote the equation 3(y + 2) = (x -
5)2. Which of the following best explains
if Sam was correct, or if he was
T
incorrect, the error that he needs to
correct.
A Sam is correct in his equation.
B Sam is incorrect. His equation should
reflect an h and k value that is the
same as the focus point.
C Sam is incorrect. His equation shows
the h and k values reversed and he
needs to square the y side of the
equation instead of the x side.
D Sam is incorrect. He forgot to multiply
the distance between the vertex and
focus points by 4.
