Answer the question.How does one decide whether a set of points is included in the domain of a function? In the range?
What will be an ideal response?
To be part of the domain, a value for x must yield a value for y. When fractions are present, values for x must be avoided that make the denominator zero. When radicals are present, values for x must be avoided that make the value of the radicand negative. The same reasoning can be used on the range.
