Question

A coordinate plane going from negative 10 to 10 in increments of 1 labeled every 5 units on the x-axis and from negative 1 to 15 in increments of 1 labeled every 5 units on the y-axis. A curve is drawn. The x-axis is labeled Time in days. The y-axis is labeled Stock Price in dollars.▼Click for Long DescA coordinate plane going from negative 10 to 10 in increments of 1 labeled every 5 units on the x-axis and from negative 1 to 15 in increments of 1 labeled every 5 units on the y-axis.

Answer 1

The value of a stock decreases at a constant rate over time.

Reason: The points (−5,6) and (5,0) lie on a line with slope (0−6)/(5−(−5)) = −6/10 = −3/5, so a linear (constant-rate) decrease fits; an exponential (constant-percentage) model cannot reach zero in finite time.
