Quizplus · Accepted Answer

The function is a linear function with a slope of 8, which means the function is defined for all real numbers. Therefore, the domain is $( - \infty , \infty )$. The graph of a linear function is a straight line, and since the domain is all real numbers, the line will extend infinitely in both directions.
