The path of a launched projectile contains the vertex (5, 120) and the point (25, 80) on the boundary. If all the experiments that followed met or exceeded this path, which quadratic inequality in standard form contains the points in the later experiments?
Answer
A
y greater-than-or-equal-to one-tenth (x + 5) squared + 120
B
y less-than-or-equal-to negative one-tenth (x + 5) squared + 120
C
y less-than-or-equal-to negative one-tenth (x minus 5) squared + 120
D
y greater-than-or-equal-to negative one-tenth (x minus 5) squared + 120
