2 Domain and Range

The set of all possible input values (x-values) for which the function is defined.

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

By identifying the lowest and highest points on the y-axis that the graph reaches.

It means that the function can accept any real number as an input.

All real numbers except x = 0, since division by zero is undefined.

By looking at the x-values that the graph covers.

The Range is y ≥ 0, since the output of x^2 is always non-negative.

Endpoints indicate the minimum and maximum values of the output (y-values) of the function.

The output values of the function are greater than or equal to -3 and less than 1.

The horizontal extent of the graph, showing all x-values for which the function is defined.
