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 …
Web23 de out. de 2024 · Explanation: STEP 1: Remember that our function, f (x), is increasing when the derivative, f '(x) > 0. So our first step is to find f '(x). f '(x) = 3x2ex +x3ex ⇒ x2ex(3 + x) STEP 2: Find the zeros of the function. x = 0,x = −3 STEP 3: Use a sign chart to determine when f '(x) > 0 at each interval.
