On which interval is the function decreasing
WebFor a rational function, you do have situations where the derivative might be undefined — points where the original function is undefined i.e. has zero in the denominator. … Web18 de ago. de 2024 · If x is > 4/3, then −3x +4 is negative, so therefore the slope ( x( −3x +4)) will also be negative. So, therefore 0 < x < 4/3 is the only interval where the original function −x3 +2x2 + 2 is increasing. Or, you can cheat, by graphing the function, and picking out the increasing interval by eye.

On which interval is the function decreasing
Did you know?
WebA function f (x) increases on an interval I if f (b) ≥ f (a) for all b > a, where a,b in I. If f (b) > f (a) for all b>a, the function is said to be strictly increasing. x³ is not strictly increasing, but it does meet the criteria for an increasing function throughout it's domain = ℝ. 2 … WebA function is called increasing on an interval if given any two numbers, and in such that , we have . Similarly, is called decreasing on an interval if given any two numbers, and in such that , we have . The derivative is used to determine the intervals where a function is either increasing or decreasing.
