Final answer:
To sketch the curve represented by the given parametric equations, we can use the descriptions provided to draw a logistic curve.
Step-by-step explanation:
To sketch the curve represented by the given parametric equations, we first need to identify the type of curve. Part A of the equation has an initial nonzero y-intercept with an upward slope that levels off at zero. Part B begins at zero with a downward slope that decreases in magnitude until the curve levels off. Part C starts at zero with an upward slope that increases in magnitude until it becomes a positive constant. This description matches a logistic curve.
A logistic curve is often plotted using calculus techniques. However, if you need to sketch it without plotting, you can use the provided descriptions to draw a curve that satisfies the given characteristics.
