Given x – 5 < (y – 8)2, which graph represents the inequality?
Answer
A
On a coordinate plane, a parabola opens up. It goes through (0, 20), has a vertex at (8, 5), and goes through (14, 14). Everything outside and below the parabola is shaded.
B
On a coordinate plane, a parabola opens down. It goes through (0, negative 10), has vertex (3, 5), and goes through (14, negative 4). Everything inside and below the parabola is shaded.
C
On a coordinate plane, a parabola opens to the right. It goes through (21, 16), has vertex (3, 8) and goes through (22, 0). Everything outside and to the left of the parabola is shaded.
D
On a coordinate plane, a parabola opens to the left. It goes through (negative 8, 15), has vertex (5, 8), and goes through (negative 10, 0).
