Consider a student’s work in determining the solution set of x > 2(y – 1)^2 – 2.
2 answers:
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.
<u>There are no errors.</u>
- Incorrect (the graph)
<u>The conclusion statement is incorrect.</u>
- Incorrect
<u>The graph of the solution set is incorrect.</u>
- Correct (the line should be dotted)
