Answer: The exponential decay is at (0,8) and the exponential growth is at (0,4)
Step-by-step explanation: The red line is the decaying line, it passes through the Y-intercept at (0,8) as shown on the graph. The blue line is the growth line, it passes through the Y-intercept at (0,4) as shown by the graph. These are the numbers you are looking for.
