The WebAssign component for this textbook engages students with immediate feedback, lecture videos, and an interactive, fully customizable eBook.

    Questions 1, 3 - 5 and 8 - 12 have Watch Its.

    Questions 4, 7, and 11 have Cengage Master It Tutorials.

    Question 4 features prime factorization grading.

    Question 8 uses the WebAssign graphing tool for graphing solutions to inequalities.

    Question 9 uses the matrix tool, which lets student define the size of the resulting matrix.

    Question 10 grades the antiderivative to enforce correct form and notation while also allowing all mathematically correct answers.

    Question 11 shows ratio grading as a probability.

    Question 12 uses a Venn diagram so students can visually see which regions they are identifying.

    View the complete list of WebAssign questions available for this textbook. This demo assignment allows many submissions and allows you to try another version of the same question for practice wherever the problem has randomized values.
