y=-0.5x-3 graph each equation, and determine domain and range, then determine if its discrete or continuous

Make a table of values.Be sure to include the domain values for which the function changes. The graph will cover all possible values of x, so the domain is all real numbers.The graph will go no higher than y = 0, so and the range is { y | y \u0013`\u0011 x ±3 ±2 ±1 0 1 g(x ) 2 0 2 4 6 \u001a\u0011
