You may want to check your work with a graphing calculator or computer. 46. \(f\left( x \right) = 36x + 3{x^2} - 2{x^3}\)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. If f ′ ( x) is not continuous where it changes sign, then that is a point where f ′ ( x) doesn't ...

Similarly, a function is decreasing on an interval if the function values decrease as the input values increase over that interval. The average rate of change of an increasing function is positive, and the average rate of change of a decreasing function is negative.Using interval notation, it is described as decreasing on the interval (3,5). • Constant: A function is constant, if as x increases (reading from left to right), y stays the same. In plain English, as you look at the graph, from left to right, the graph goes flat (horizontal). The graph has a slope of zero.f(x) is decreasing if derivative f′(x) <0, f(x) is constant if derivative f′(x) = 0. A critical number, c, is one where f′(c) = 0 or f′(c) does not exist; a critical point is (c,f(c)).

Increasing and Decreasing Intervals Knowing where a graph increases, decreases, and is constant is useful when sketching a graph. Increasing • The interval of a function is rising from left to right. • The x and y values are getting larger. • We denote the interval using interval notation with x-values.Notice how the parabola doesn't increase or decrease at the same rate over the whole graph. So, we need a way to calculate the rate of change for a quadratic expression. Let's talk about it :) ... the way to evaluate rates of change is you have to look at a change in height over the same length time intervals. Graph courtesy of Desmos.
