What is the average rate of change from −3 to 0 of the function represented by the graph?

An inverse variation function graphed on a coordinate plane. The horizontal x-axis ranges from negative 4 to 1 in increments of 1. The vertical y-axis ranges from negative 1 to 4 in increments of 1. Moving from left to right, the branch is in the second quadrant and passes through begin ordered pair negative 3 comma 2, begin ordered pair negative 2 comma 1 end ordered pair, begin ordered pair 1 comma 0.66 end ordered pair, begin ordered pair 0 comma 0.5 end ordered pair and begin ordered pair 1 comma 0.4 end ordered pair.
