The graph that represents an exponential decay function is the second graph.
- For you to determine which of the graphs represents an exponential decay, we will need to check the curve that passes through or lies on the x-axis.
- From both figures, we can see that the curve of the second graph almost lies on the x-axis as it curves downwards. This makes it an exponential decay function.
Hence the graph that represents an exponential decay function is the second graph.
