Interpret quadratic/exponential expressions by treating sub-expressions as meaningful units.
Use a difference table to bracket a solution of f(x) = g(x)
Problem
Interpret and evaluate \(P=100(1.1)^3\). Identify the initial value, interval factor, percent change per interval, and number of intervals; compute the compounded multiplier before the final amount.
Big Picture
What this problem is really about
An exponential expression separates into a starting amount, an interval multiplier, and a count of factor applications. We’ll translate the multiplier into a percent change, compute the compounded multiplier before applying it to the start, and distinguish repeated multiplication from simply adding the interval percentages.
