WebSep 18, 2024 · Yes, if f (x) is assumed concave up, f' (x) must be increasing on the concaved up interval, and therefore, f'' (x) must be positive on this same interval. -If f' (x) is increasing, it could still be negative until it would pass a critical point (f' (x) = 0) and then f' (x) … WebDec 20, 2024 · The key to studying f ′ is to consider its derivative, namely f ″, which is the second derivative of f. When f ″ &gt; 0, f ′ is increasing. When f ″ &lt; 0, f ′ is decreasing. f ′ has relative maxima and minima where f ″ = 0 or is undefined. This section explores how knowing information about f ″ gives information about f.

WebIncreasing and Decreasing Functions The slope determines if the function is an increasing linear function, a decreasing linear function, or a constant function. f(x) = mx + b is an increasing function if m &gt; 0. f(x) = mx + b is a decreasing function if m &lt; 0. f(x) = mx + b is a constant function if m = 0. Example 2 WebI'm getting better at using trig functions, but this problem has me up against a wall. As I understand it, to find if a function is increasing or decreasing over a given interval, select a number inside that interval and if the result is greater or less than zero, the interval is increasing and decreasing, respectively.
