Derivative as a limit: numerical

Olivia wants to find the derivative of g(x)=5exg(x)=-5e^x at the point x=0x=0.
Her table below shows the average rate of change of gg over the intervals [x,0][x,0] or [0,x][0,x] for xx-values that get increasingly closer to 00:
xxIntervalAverage rate of change, g(x)g(0)x0\dfrac{g(x)-g(0)}{x-0}
0.1-0.1[0.1,0][-0.1,0]4.7581-4.7581
0.01-0.01[0.01,0][-0.01,0]4.9751-4.9751
0.001-0.001[0.001,0][-0.001,0]4.9975-4.9975
0.0010.001[0,0.001][0,0.001]5.0025-5.0025
0.010.01[0,0.01][0,0.01]5.0251-5.0251
0.10.1[0,0.1][0,0.1]5.2585-5.2585
From the table, what does the derivative of g(x)=5exg(x)=-5e^x at x=0x=0 appear to be?
  • Your answer should be
  • an integer, like 66
  • an exact decimal, like 0.750.75
  • a simplified proper fraction, like 3/53/5
  • a simplified improper fraction, like 7/47/4
  • a mixed number, like 1 3/41\ 3/4
