Question

Consider a student’s work in determining the solution set of x > 2(y – 1)^2 – 2.

Answer 1

Answer:

Its C

Step-by-step explanation:

Answer 2

Answer:

• C. The graph of the solution set is incorrect.

Step-by-step explanation:

• Solution is right, properly substituted x- and y-values, no mistakes.
• Conclusion is right, the point within the solution set.
• The only mistake is the graph, with > sign the line of the graph is not included into solution, therefore should be dotted.

There are no errors.

• Incorrect (the graph)

The conclusion statement is incorrect.

• Incorrect

The graph of the solution set is incorrect.

• Correct (the line should be dotted)

The substitution of x and y values is incorrect.
