   What is a lower bound in math?

   • A lower bound is a number that is numerically lower than or equal to to all the possible values of a function, variable or set. For example, if we have a number x, then a lower bound of x would be any number that is less than or equal to x. There are many ways to formulate lower bounds. One way is to use a graph. Another way is to use inequalities.

   What is a mathematical bound?

   • Bounds are often used to describe the range of possible values for a variable, or the range of possible outcomes for a function. Bounds can be used to find the maximum or minimum value of a function, or to prove that a function is continuous. A mathematical bound is a limit that a function or variable can approach but never beyond.

   What does bounded above mean?

   • A set with an upper (respectively, lower) bound is said to be bounded from above or majorized (respectively bounded from below or minorized) by that bound. The terms bounded above (bounded below) are also used in the mathematical literature for sets that have upper (respectively lower) bounds.

   What is upper bound & lower bound?

   • Upper bound: a value that is greater than or equal to every element of a set of data. But be careful! 2 is also a lower bound (it is less than any element of that set), in fact any value 3 or less is a lower bound. Likewise any value 22 or above is also an upper bound, such as 50 or 1000.

   What are the two types of bounds?

   • There are two types of bounds that are commonly used in mathematics, namely upper bounds and lower bounds. The upper bound of a function or variable is its highest value, whereas the lower bound of a variable is its minimum value. Both of these types are further explained in next paragraphs.

   What is the upper and lower bound of a number?

   • Stating 24 as the upper bound when a number is 20 to the nearest 10 . Remember that there are numbers bigger than 24 that would round down to 20 such as 24.9. The upper and lower bounds (when rounding to a multiple of 10 ) should always end in 5 . For example, Using the place value of 100 when a number is 700 to the nearest 10.

   Upper and lower bounds are the maximum and minimum values a number could have been before it was rounded. The lower bound is the smallest value that would round up to the estimated value. The upper bound is the smallest value that would round up to the next estimated value. They can also be called limits of accuracy.

   The upper and lower bounds of a rounded number are the biggest and smallest values that the number could have been before it was rounded. We often round numbers to a given degree of accuracy, for example to the nearest 1010 or to 11 decimal place.
