**Max and Min of a Cubic Without Calculus â€“ The Math Doctors**

We postulate that if there is a maximum followed by a minimum, or a minimum followed by a maximum, then there must be a point of inflection in between. We prove this by looking at a general cubic equation f(x) like in the first graph, and treating its derivative as a new function.... If it had two, then the graph of the (positive) function would curve twice, making it a cubic function (at a minimum). If it had zero, the function would not curve at all, making it not a quadratic. If it had three or more, it would be a quartic function (at a minimum).

**Exploring Maximum and Minimum Values of Polynomial Functions**

Polynomials of even degree have a minimum of 1 turning point and a maximum of n-1. So, in part, it depends on the definition of "turning point", but in general most people will go by the first definition.... Picking nearby points to see if a critical point is a maximum or minimum can be hazardous because the curve might do things you don't expect. This cubic is very close to â€¦

**Max and Min of a Cubic Without Calculus â€“ The Math Doctors**

Answer to: Find a cubic function f(x) = ax3 + bx2 + cx + d that has a local maximum value of 4 at x = -4 and a local minimum value of 0 at x = 2....... is a third-degree polynomial function (also known as a cubic function; a second-degree polynomial function is also called a quadratic function) The constant term (27, in this case) is a coefficient times . x. raised to the zero power. This module illustrates methods of finding local maxima and minima of polynomial functions. One method uses calculus, specifically the concept that the first

**How to find the maximum and minimum value of this cubic**

The function takes on a minimum value when x is equal to 2. And the function took on a maximum value when x was equal to negative 2. And the function took on a maximum â€¦... The function takes on a minimum value when x is equal to 2. And the function took on a maximum value when x was equal to negative 2. And the function took on a maximum â€¦

- A cubic function has no maximum and minimum when its derivative (which is a quadratic) has either no real roots or has two equal roots. Specifically, if [math]y = ax^3 + bx^2 + cx + d[/math] is your cubic function,
