A teacher poses the following problem of algebra to her class: "Does the graph x = y2 ever intersect the graph of x = y2 + 2? What are the different ways you would use to test your conjecture? Would your conjecture hold true for other equations of the form x = y2 + b." Which of the following statement/statements is/are correct in the given context? (a) One of the learning outcomes of posing this question is comparison and analysis of quadratic equations. (b) Teacher should focus only on getting the solution that the two graphs will not intersect. (c) The teacher can assess the reasoning skills of students. (d) Such questions confuse the students and hence should be discouraged in a mathematics classroom. Choose the correct option:-

(b) Teacher should focus only on getting the solution that the two graphs will not intersect. (c) The teacher can assess the reasoning skills of students. (d) Such questions confuse the students and hence should be discouraged in a mathematics classroom. Choose the correct option:- Correct Answer (a) and (c)
Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression. Quadratic equations are also a part of algebra. Key Points
The objective and reason behind the question posed by the teacher in the above example is
- Teachers can know if the students can apply the knowledge they gained in different situations.
- One of the learning outcomes of posing this question is the comparison and analysis of quadratic equations.
- The teacher can assess the reasoning skills of students.
- Teachers can differentiate the students who learned the concept through understanding from the ones who learned through memorization.
Hence (a) and (c) are the correct options.Additional Information
On the other hand, the remaining two options are wrong as they indicate that such questions will confuse the students and teachers should only focus on the correct answers which are not the objectives of mathematics.
