WebFor each of the following functions, find all critical points. Use a graphing utility to determine whether the function has a local extremum at each of the critical points. \(f(x)=\frac{1}{3}x^3−\frac{5}{2}x^2+4x\) \(f(x)=(x^2−1)^3\) \(f(x)=\frac{4x}{1+x^2}\) Solution. a. The derivative \(f'(x)=x^2−5x+4\) is defined for all real numbers ... Web2. Saying sin ( 3 x) = 0 means 3 x = k π, for some integer k. Therefore x = k π / 3 and you just have to determine all integers k such that k π / 3 ∈ [ − π, π]. Now. − π ≤ k π 3 ≤ π. is equivalent to. − 3 ≤ k ≤ 3. so we have seven critical points. For telling apart the points of maximum and minimum, the simplest way is ...

Example 2 Find the critical points of the function {eq}f(x) = (12/25)x^218x^8 {/eq Webthe critical point. The point x 0 is a local minimum. Similarly, if f00(x 0) <0 then f0(x) is positive for xx 0. This means that the function increases left from the critical point and increases right from the critical point. The point is a local maximum. Example: The function f(x) = x2 has one critical point at ... cyclopithecus
