is a squared number a function of a number?
YES..SINCE Y=X^2...GIVES UNIQUE IMAGES...THAT IS SAME VALUE OF X WILL NOT GIVE RAISE TO 2 DIFFERENT VALUES OF Y.THAT IS Y1 IS NOT EQUAL TO Y2 ,IT IMPLIES X1 IS NOT EQUAL TO X2.
can a squared number be reduced?DO YOU MEAN FINDING A QUARE ROOT...IN THAT CASE YES IF SQUARED NUMBER IS POSITIVE..PLEASE CLARIFY WHAT YOU MEAN BY REDUCED?
