Final answer:

Even power functions symmetry, linear programming feasible region, functions classification, problem-solving approach in teaching


Explanation:

Even power functions are classified based on symmetry as:

  1. A. Symmetry about the x-axis
  2. B. Symmetry about the y-axis
  3. C. Symmetry about the origin
  4. D. Symmetry about the line y = x

The feasible region in linear programming is the area where all constraints are satisfied. It is not based on the number of constraints but on meeting all the given conditions.

In terms of functions, a vertical line passing through x = 4 is not a function as it fails the vertical line test, unlike the other provided equations.

The problem-solving approach in teaching is a method that encourages learners to 'do mathematics' and engage in critical thinking, not just memorization or lectures.
