Free SAT Nonlinear functions Practice Questions
Nonlinear function questions on the SAT center on quadratics and exponentials: reading a vertex, a zero, or a growth factor directly from the form an expression is written in, and interpreting what those mean in context.

Preparing the question set…
Try three questions before signing in. Your first miss opens a hint; the full solution stays sealed until you solve or reveal it.
How the SAT tests nonlinear functions
You identify maxima and minima from vertex form, roots from factored form, and growth or decay rates from an exponential's base.
Where the points go
Expanding to standard form and losing the information the given form was handing you, and reading a vertex sign backwards.
Every question you miss here is added to your mistake log with the specific error identified, and brought back after three days and again after fourteen — no screenshots, no error journal to keep.
