Hey Im trying to plot this set of data:

0 0
10 0.6
20 1.01
30 1.428
40 2
50 2.3
60 2.57
70 2.8
80 3.05
90 3.35
100 3.54
110 3.73
120 3.9
130 4.08
140 4.25
150 4.39
160 4.53
170 4.65
180 4.754
190 4.846
200 4.943
210 5.011
220 5.111
230 5.175
240 5.23
250 5.295
260 5.356
270 5.407
280 5.441
290 5.495
300 5.526

The expected exponential fit is about y=6-6e^(x/100). however, when I try to find put an exponential fit with excel, it makes the fit increase instead of decrease. How do I fix this?
