Model exponential decay
A quantity is modelled by \(N(t)=1200(0.8)^t\). State the initial value, state the multiplier per time step, and predict \(N(2)\).
Worked practice: exponential model
Identify the starting value and growth factor, then use the model for the prediction.
Write a full answer
Now write the response in full, in your own words — this is what the exam asks for. The AI marks it on the same moves you built above (focus, evidence, technique, judgement) and gives feedback on reasoning, evidence, and expression.
