WebIron Programming. A function takes any input within its domain, and maps this to 1 output. The domain of a function is what input values it can take on. For an example, the function f (x)=1/x cannot take on x values of x=0 because that would make the function undefined (1/0 = undefined). The range is what possible y values a function can take on. http://www.reflexmath.com/

WebJan 6, 2024 · Example 1: Prove that the relation R is an equivalence type in the set P= { 3, 4, 5,6 } given by the relation R = { (p, q): p-q is even }. Solution: R = { (p, q): p-q is even }. Where p, q belongs to P. Reflexive Property : From the provided relation p – p = 0 =0. And 0 is always even. Therefore, p – p is even. Hence, (p, p) relates to R
