In an undergraduate college-level course, the TA grades student essays on a topic of their choosing. When grading, the TA goes through the student submissions in a way that is sorted alphabetically by the students’ last name. The TA finds they typically grade the first few submissions higher compared to the ones at the end. Which change best reduces the risk of bias introduced by the sorting procedure?

Use the Equation Editor to format your answer where necessary: If you need the infinity symbol:

Determine if the graph is a function Show why or why not in your written work for full credit.

If f(x) is defined as Graph the function and indicate the domain and range in your written work for full credit. The intercept(s) is/are [intercepts]  (Type an ordered pair. Use a comma to separate answers as needed.)

Use this function to answer the following questions:

Use the Equation Editor to type the equation in standard form of the circle with center at (-2,1) and radius of 4.  

Use the Equation Editor to type the equation (in standard form) of the circle with center at (8,6) and tangent to the y-axis.  

Remember to start numbering questions with #2. Simplify all answers. Show all work.

List the intercepts for x2 + y − 100 = 0 and test for symmetry. Intercepts: [intercepts]  (Type an ordered pair. Use a comma to separate answers as needed.) Is the graph symmetric with respect to the x-axis? [x_axis]  (Y or N) Is the graph symmetric with respect to the y-axis? [y_axis]  (Y or N) Is the graph symmetric with respect to the origin? [origin]  (Y or N)
