Researchers collect data on a certain bird in their region. They want to know if there is a relationship between the number of chirps the bird does and the temperature outside. What trend, if any, do the researchers notice based on the data below

The image above is that of an exponential function. Considering the shape of the graph which is a curve and looking at the graph in question we can conclude there is a relationship between the number of chirps the bird does and the temperature outside. Also, it follows an exponential trend.
