What does bounded above or below mean in precaculus?
A set is bounded above by the number
A set is bounded below by the number
A set of natural numbers
This set can be written as
This set is bounded above by
suppose you have a set S .
Suppose you have a set of values containing values between a real number a and b including a and b .
each value in above mentioned set of values is more than or equal to a and similarly, each value is less than or equal to b.
Thus the set is said to be bounded , where ,
a is said to be the lower bound of set and b the upper bound of set .
if the set is :
still a is the lower bound and b the upper bound .
