Which graph represents the parametric equations x = 3t and y = t3 – 1, where –2 ≤ t ≤ 3?
Answer
A
On a coordinate plane, a curve starts at (negative 6, 3), curves down through (negative 4, 0), has inflection point (0, negative 1), and curves down through (8, negative 10).
B
On a coordinate plane, a curve starts at (negative 9, 13), curves down through (negative 3, 0) to inflection point (0, negative 1), and then curves down to (6, negative 5).
C
On a coordinate plane, a curve starts at (6, 3), curves down through (4, 0) to inflection point (0, negative 1), and curves down through (negative 8, negative 10).
D
On a coordinate plane, a curve starts at (negative 6, negative 5), goes through (negative 4, negative 2) to inflection point (0, negative 1), and then curves up through (3, 0) to (9, 13).
