Four functions are given below. Either the function is defined explicitly, or the entire graph of
the function is shown. For each, decide whether it is an even function, an odd function, or
neither.
Solution
function r = odd function because its not have mirror image
function s = even fucntion
g(x) = odd because g(x) is not equal to g(-x)
h(x) is even function
h(x) = h(-x)
