Apr 10, 2019 · $f (x)=g (x)+o ( (x-4)^ {3})$ and $o ( (x-4)^ {3}) \rightarrow 0$ so I think I can say that $f,g$ has extremes in the same points. However I don't know if I'm right, and if so how can …

f0(x) = 3x2 > 0 on both sides of x = 0, so by First Derivative Test, f(x) has no local extreme value at x = 0. f(x) cannot have local extreme value anywhere else, because x = 0 is the only critical …

1) If f'(x) > 0 for all x on (a,c) and f'(x)<0 for all x on (c,b), then f(c) is a local maximum value. 2) If f'(x) < 0 for all x on (a,c) and f'(x)>0 for all x on (c,b), then f(c) is a local maximum value. 3) If …

Depending on c, the function f(x) = x4 cx2 has either one or three critical points. Use the second derivative test to decide: a) For c = 1, nd and determine the nature of the critical points.

The term “local extrema” is the plural form of “local extremum,” referring to extreme values in a specific domain for a function. Since trigonometric functions are periodic, they may change …

If f0(x) changes from positive to negative at c, then has a local max at x = c .
