Why it matters

• Use exponent laws to simplify fast and avoid common mistakes.
• Model growth and decay in populations, money, and science.
• Understand compound interest and how time changes everything.
• Use half-life to explain medicine, chemistry, and radioactive decay.
• Graph exponentials and read key features (intercepts, asymptotes, rate).
• Recognize how exponential change shapes the world around us.

Tip: Look for a constant multiplier — that’s a clue you’re in exponential territory.
