$\"\"$

The function is $\"\"$ .

The above function is piecewise function.

Graph the constant function $\"\"$ for $\"\"$ . Since 0 does not satisfy this inequality, began with an open circle at $\"\"$ and draw a horizontal ray to the left.

Graph the linear function $\"\"$ for $\"\"$ . Since 0 does satisfy this inequality, stop with a closed circle at $\"\"$ . $\"\"$

The graph of function $\"\"$ is

$\"graph$

The function is defined for all values of x, so the domain is all real numbers.

The values that are y - coordinates of points on the graph are $\"\"$ and all real numbers less than or equal 2. So the range is $\"\"$ . $\"\"$

The domain of the function is all real numbers and its range is $\"\"$ , and its graph is
