WebA cubic function with real coefficients has at least one real root, since complex roots come in conjugate pairs. A cubic function can have 1 real root (repeated 3 times, or 1 real root …
WebUnlike quadratic functions, cubic functions will always have at least one real solution. They can have up to three. For example, the function x (x-1) (x+1) simplifies to x 3 -x. From the initial form of the function, however, we can see that this function will be equal to 0 when x=0, x=1, or x=-1. WebSep 28, 2015 · It appears that there are 3 extrema,because f ′ ( x) = 0 is a cubic equation. But in the answer in the book,exactly one extremum is the answer.

WebNov 16, 2024 · The function will have an absolute maximum at x = d x = d and an absolute minimum at x = a x = a. These two points are the largest and smallest that the function will ever be. We can also notice that the absolute extrema for a function will occur at either the endpoints of the domain or at relative extrema. pony express aysoWebhas a relative minimum point at x=2 x = 2 . f f is undefined at x=1 x = 1 , so it doesn't have an extremum point there. Problem 1 Jason was asked to find where f (x)=2x^3+18x^2+54x+50 f (x) = 2x3 +18x2 +54x +50 has a relative extremum.
