The graph of the derivative of a function f is shown below.
(a) Over what intervals is f(x) increasing? decreasing?
Observing the figure, we can understand that the derivative of f(x) is positive when x belongs to (-∞, -1)U(0, 2) U(2, ∞), and the derivative is negative for x in (-1, 0)
Why?
The function increases when the ...
