Increasing and Decreasing Intervals

If f(x) is continuous on such that f’(c) ≤ 0 [f’(c) > 0] for each c ∈ (a, b), then f(x) is monotonically (strictly) decreasing function on [a, b]. If f(x) and

Increasing and Decreasing Functions Definition

So f ″ ( x) is increasing in x. Since f ″ ( 0) = 0, it follows that f ″ ( x) > 0 for all x > 0. This in turn, implies that − 1 + ( x 2 / 2) + c o s ( x) > 0 for all x > 0 since f ′ ( 0) = 0. Since, f ′ ( x)

Increasing & decreasing intervals review

The derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′ (x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′ (x) < 0 at each
