Min( <List> ): Returns the minimum of the numbers within the list.; Example: Min({-2, 12, -23, 17, 15}) yields -23.

Note: If the input consists of non-numeric objects, then this command considers the numbers associated with those objects. If you have a list of segments for example, the command Min( <List> ) will yield the minimum segment length.
Min( <Interval> ): Returns the lower bound of the interval.; Example: Min(2 < x < 3) yields 2 .

Note: Open and closed intervals are not distinguished.
Min( <Number>, <Number> ): Returns the minimum of the two given numbers.; Example: Min(12, 15) yields 12.

Min( <Function>, <Start x-Value>, <End x-Value> ): Calculates (numerically) the local minimum point for function in the given interval. Function should be continuous and have only one local minimum point in the interval (and no local maximum).; Note: For polynomials you should use the Extremum Command.; Example: Min(exp(x) x^3,-4,-2) creates the point (-3, -1.34425) .

Min( <List of Data>, <List of Frequencies> ): Returns the minimum of the list of data with corresponding frequencies.; Example: Min({1, 2, 3, 4, 5}, {0, 3, 4, 2, 3}) yields 2, the lowest number of the first list whose frequency is greater than 0.

Note:

If you want the minimum of two functions f(x) and g(x) then you can define (f(x) + g(x) - abs(f(x) - g(x)))/2
See also Max Command, Extremum Command and Function Inspector Tool.

CAS Syntax

Min( <Function>, <Start x-Value>, <End x-Value> )

Unlike in the Algebra View, this syntax will give the minimum over the interval, including endpoints

Example:

Min(x^2,-1,2) yields the point (0,0)
Min(-x^2,-1,2) yields the point (2,-4)
