Increasing on: (0,∞) ( 0, ∞)Notice how the slopes of the tangent lines, when looking from left to right, are increasing. If a function is decreasing and concave up, then its rate of decrease is slowing; it is "leveling off." If the function is increasing and concave up, then the rate of increase is increasing. The function is increasing at a faster and faster rate.f ′ can only change sign at a critical number. The reason is simple. If f ′ ( x) is continuous and it changes sign, then it has to pass through 0 on its way from negative to positive (or vice versa ). That's the Intermediate Value Theorem.

These intervals represent a plausible domain for the parameter given the characteristics of your sample data. Confidence intervals are derived from sample statistics and are calculated using a specified confidence level.All defined intervals on a continuous graph either increase, decrease, or stay constant. Intervals are identified from the x-value of the point where y starts to increase, decrease, or stay constant, and by the x-value where the direction changes when observing left to right.
