This domain focuses on equivalent expressions and nonlinear equations, systems, and functions.
Recognizing the Question Type
Section titled “Recognizing the Question Type”| Question type | What to look for |
|---|---|
| Equivalent expressions | Factoring, expanding, combining fractions, or rewriting an expression without changing its value |
| Nonlinear equation in one variable | Quadratic, exponential, radical, rational, or absolute-value expressions with one unknown |
| System of equations | Two relationships, with at least one nonlinear, that must be satisfied together |
| Nonlinear function | A curved graph or a rule involving powers, roots, exponentials, or rational expressions |
