Nonlinear equations in one variable and systems of equations in two variables

SAT MathAdvanced Math · 139 questions

Nonlinear equations in one variable and systems of equations in two variables questions extend algebra into nonlinear territory — quadratics, exponentials, polynomials, and rational expressions. The key skills are rewriting expressions in equivalent forms and connecting equations to features of their graphs, like the vertex, intercepts, and end behavior. When the algebra gets heavy, graphing in Desmos is often the fastest route to intersections and zeros.
