Web(b) How many local extrema can a polynomial of degree n have? (a) Sketch the graph of a function that has two local maximum values, one local minimum, and no absolute minimum. (b) Sketch the graph of a function that has three local minimum values, two local maximum values, and seven critical numbers. algebra 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.
WebSOLVED:A cubic function is a polynomial of degree 3; that is, it has the form f (x) = ax^3 + bx^2 + cx + d, where a ≠ 0 . (a) Show that a cubic function can have two, one, or no critical number (s). Give examples and sketches to illustrate the three possibilities. (b) How many local extreme values can a cubic function have? WebDec 20, 2024 · While quadratics can be solved using the relatively simple quadratic formula, the corresponding formulas for cubic and fourth-degree polynomials are not simple enough to remember, and formulas do not exist for general higher-degree polynomials. Consequently, we will limit ourselves to three cases in this section:
