Students who have completed 8th grade math should be able to do all but which of the following?

Students who have completed 8th grade math are expected to have a solid understanding of several key concepts and skills. While they should be able to express numbers in scientific notation, use the Pythagorean theorem to solve real-life problems, and understand how to represent 3D figures from multiple perspectives, sketching quadratic functions typically goes beyond the standard curriculum expectations for this grade level.

Sketching quadratic functions involves understanding not only the concept of parabolas but also being able to identify vertex, axis of symmetry, and intercepts, which may not be a central focus in the 8th-grade math curriculum compared to other foundational skills. Therefore, it might be anticipated that while students can address some aspects of quadratic equations, the ability to sketch these functions with precision would not yet be expected to the same degree as the other skills mentioned.
