Graph x + 4 = –8(y – 2)2.
Answer
A
On a coordinate plane, a parabola opens to the right. It goes through (4, 3), has a vertex at (negative 4, 2), and goes through (4, 1).
B
On a coordinate plane, a parabola opens to the left. It goes through (negative 6, 1.5), has a vertex at (negative 4, 2), and goes through (negative 6, 2.5).
C
On a coordinate plane, a parabola opens to the right. It goes through (6, negative 1.5), has a vertex at (4, negative 2), and goes through (6, negative 2.5).
D
On a coordinate plane, a parabola opens to the left. It goes through (negative 4, negative 1), has a vertex at (4, negative 2), and goes through (4, negative 3).
