Quadratic, exponential, and polynomial functions on the Digital SAT.
Nonlinear function questions — especially quadratics and exponentials — appear at the top of the hard Module 2. You need to be able to factor, complete the square, use the vertex form, and interpret growth or decay rates.
These are real practice questions pulled from our Digital SAT bank. Try each one before reading the highlighted correct answer.
