f x x 1 x 2 2 increasing or decreasing

f x x 1 x 2 2 increasing or decreasing Strictly speaking it is neither f 1 0 is a constant However f x 2 x 2 x 1 x 2 2 so f 1 1 Note that f is continuous near 1 So f x is positive near 1

Want to learn more about increasing decreasing intervals and differential calculus Check out this video Example 1 Let s find the intervals where f x x 3 3 x 2 9 x 7 is At x 0 we have f x 1 x 2 2 cos x 0 and f x x sin x which at x 0 is also 0 But note that for all x geq 0 we have f x 1 cos x geq

Decreasing Functions The y value decreases as the x value increases For a function y f x when x1 x2 then f x1 f x2 Decreasing when x1 x2 then f x1 f x2 Strictly Decreasing Notice that f x 1 is In summary f is increasing on the set infty 1 cup 3 infty and is decreasing on the set 1 1 cup 1 3 Since at x 1 the sign of f switched from

Graph the function latex f left x right x 3 6 x 2 15x 20 latex to estimate the local extrema of the function Use these to determine the intervals on which the function is increasing and decreasing If for any two points x 1 x 2 a b such that x 1 x 2 there holds the inequality f x 1 f x 2 the function is called increasing or non decreasing in this interval Figure 1 If

The interval is increasing if the value of the function f x increases with an increase in the value of x and it is decreasing if f x decreases with a decrease in x In this article we An example of this would be f x x then f x x f x 0 at x 0 but f x x is increasing for all x because at x 0 the slope is 0 but it s neither a min or a max
