Question

recognizing exponential decay
which graph represents exponential decay?

Explanation:

Exponential decay graphs are decreasing curves that approach a horizontal asymptote (usually the x-axis) as x increases, starting from a high value on the left. Linear graphs (first and fourth options) have constant slopes, not exponential behavior. The second graph shows exponential growth (increasing curve). The third graph matches the shape of exponential decay.

Answer:

The third graph (the decreasing curve that approaches the x-axis as x increases)
