Suppose a curve is given by the parametric equations x=f(t), y=g(t), where the range of f is [2, 7] and the range of g is [1, 4]. What can you say about the curve? You must select all correct choices to get full credit on this problem.
A. The curve is the line with endpoints (-1, -1) and (4, 10).
B. The curve must lie inside a circle with center (-1, -1) and radius 0.5.
C. The curve is completely contained in the rectangle [-1, 4] by [-1, 10].
D. The curve is a circle with center (-1, -1) and radius 10.
E. The curve must lie outside the rectangle [-1, 4] by [-1, 10].
F. Nothing can be said about the curve.
