Power Regression Formula Doesn't Work

According to the graph, the Power Regression maps closest to the empirical data.
120 122 124 126 128 130
1260 570 270 120 60 30

For some reason the Power Regression formula itself doesn't seem to work. The power value is so large that the results for y remains the same for all point.
Above is the data-set. Hoping you may know how to solve the issue. Thank you!
