Upper and Lower Bounds for Approximation

This video tutorial explains the concept of upper and lower bounds in approximation, particularly when numbers are rounded. It covers how these bounds define the range within which the actual value of a rounded number can fall. The tutorial provides examples, explaining that the lower bound is the smallest value that rounds to the estimated value, while the upper bound is the smallest value that rounds up to the next estimated value. The video also includes practice questions to reinforce understanding.

What is the relationship between the actual value and the upper and lower bounds?

Provide an example of rounding a number to the nearest hundred and explain the bounds.
