Function Discrete Math Examples

For example a discrete function can equal 1 or 2. A function f. For example p 7 3 210 we can see that this yields the number of ways 7 items can be arranged in 3 spots there are 7 possibilities for the first spot 6 for the second and 5 for the third for a total of 7 6 5.

The domain and codomain are both the set of integers.

Function discrete math examples. A discrete function is a function with distinct and separate values. 1 2 3 a b c g. A function f. Z rightarrow z g x x 5.

However the range is only the set of integer multiples of 3. This means that the values of the functions are not connected with each other. Z rightarrow z f x x 2 is not invertiable since this is not one to one as x 2 x 2. The permutation function yields the number of ways that n distinct items can be arranged in k spots.

The function f is called invertible if its inverse function g exists. Z rightarrow z f x x 5 is invertible since it has the inverse function g. The following are all examples of functions. 1 2 3 a b c.

Defined by f n 3n. F n 3 n.
