Write an expression in words that describes the set of numbers given by the interval (–6, 7). a. all real numbers greater than –6 and less than 7 b. all real numbers less than –6 and greater than 7 c. all real numbers greater than or equal to –6 and less than or equal to 7 d. all real numbers less than or equal to –6 and greater than or equal to 7

For this case we have the following interval:

The equivalent expression for this interval is given by:

Therefore, we have the following inequations:

From where, we can conclude:

All real numbers greater than -6 and less than 7

An expression in words that describes the set of numbers given by the interval (-6, 7) is:

A. All real numbers greater than -6 and less than 7
