Round 1 — Equation from two points (\(y\)-intercept given)

Cut along dashed lines · Distribute one card per partner
★Round 1 · Problem Card
\(f\) is an exponential function. Find an equation defining \(f(x)\). Show your reasoning.
Ask your partner for the information you need. Explain why you need it.
▲Round 1 · Data Card
The graph of \(f\) passes through \((0, 200)\) and \((2, 1012.5)\).
Before answering, ask: "Why do you need to know that?" Give only what is on this card.
