Exponential functions SAT practice questions

Exponential functions questions usually reward a repeatable process. For this topic, that process means growth, decay, and repeated multiplication. The Digital SAT often hides a familiar skill inside a short context, table, graph, or answer-choice comparison.

Before solving, name what the question is asking for. Then write the smallest useful setup: an equation, a grammar test, a claim from the passage, or a relationship from the data. That setup protects accuracy and prevents answer choices from steering your thinking.

Start with untimed practice until the method feels automatic. Once accuracy is steady, add a timer and review every miss by cause: setup error, concept gap, reading mistake, or rushed arithmetic.

After each set, write one sentence explaining the deciding clue. That sentence is more useful than copying a long solution because it trains the recognition you need on test day.
