Find ten further examples of functions five mathematical fiv

Find ten further examples of functions, five mathematical, five connected with everyday life. In each case, be sure to specify the domain, the codomain, and the rule, and verify that your example is indeed a function. Give four functions, two mathematical two non-mathematical. specifying each by two different rules. Find, it possible, examples of functions having the following properties: Most hand calculators provide a squareroot function y/for real numbers x. Give a precise definition of this function.

Solution

if m,n are odd then f(m) < f(n) : m<n

if m, n are even then f(m) = f(n)

now problem says that if one of m,n is even and the other odd then in this case f(m) > f(n) becuase it satisfies the abovethree properties given in the problem.and m < n if m>n in this case we acn not establish any relation .
