We can define the derivative of a function in the point x as the slope of the tangent line to the graph at that point.
Thus to estimate the value of each derivate we just need to look at the graph and estimate the slope.
Another way can be using the aproximate slope, for example, if we want to look at f'(0), then we need to analyze a small interval that contains 0, for example we can use the interval [a, b]
Then we can estimate:
[tex]f'(0) = \frac{f'(1) - f'(-1)}{1 - (-1)} = \frac{1 - 5}{2} = -2[/tex]
Now we can do the same for all the others.
for f'(1) we don't need to analyze an interval, we can see that we have a minimum, thus, the value of the derivative must be zero:
f'(1) = 0.
For f'(2) we can analyze the interval [1, 3]
We can get:
[tex]f'(2) = \frac{f(3) - f(1)}{3 - 1} = \frac{4 - 1}{2} = 3/2[/tex]
For f'(3) we can analyze the interval [2, 4]
[tex]f'(3) = \frac{f(4) - f(2)}{4 - 2} = \frac{5 - 2}{4 - 2} = 3/2[/tex]
For f'(4) we can see that we have a maximum, thus the slope is zero,
f'(4) = 0.
For f'(5) we can analyze the interval [4, 6]
[tex]f'(5) = \frac{f(6) - f(4)}{6 - 4} = \frac{3 - 5}{2} = -1[/tex]
