What is the definition of RANGE in a function?

Back

The RANGE of a function is the set of all possible output values (y-values) that the function can produce.

If a graph shows a DOMAIN of -1 < x < 4, what does this mean?

Back

It means that the function is defined for x-values greater than -1 and less than 4, but not including -1 and 4.

What is the difference between a closed interval and an open interval in DOMAIN and RANGE?

Back

A closed interval includes its endpoints (e.g., [a, b]), while an open interval does not include its endpoints (e.g., (a, b)).
