Answer:
Based on the results it is expected that the slope of the tangent line at the point (0.5,10) is -20.
Step-by-step explanation:
To see that compute, the slopes for the given points as follows:
1. For we have:
2. For we have:
3. For we have:
4. For we have:
So, we observe that the slope of the tangent line at is close to the value -20.
The graph shown below is useful to see the secant lines that approximates the tangent line.
