Frequently Asked Questions
The domain is the set of all possible input values (x) for which the function is defined. For example, for f(x)=sqrt(x), the domain is [0, ∞) because the square root of a negative number is not real.
The range is the set of all possible output values (y) that the function can produce. For f(x)=x^2, the range is [0, ∞) because squares are always non-negative.
It evaluates the function at many sample points to determine the valid x-values and corresponding y-values, then displays the intervals. For complex functions, it may not be exact but gives a good approximation.
