Study Notes
Exponential Functions and Graphing
- Graph for y = 5(1/2)^x + 4 corresponds to Option C.
- Graph for y = 4(1/6)^x + 2 corresponds to Option A.
Exponential Decay and Half-life
- Half-life of a radioactive material is 42 days.
- Initial mass of the material is 49 kg.
- Exponential decay function: y = 49(1/2)^(1/42)x.
- Remaining mass after 8 days: approximately 42.940 kg.
Evaluating Exponential Functions
- For the function y = e^x, e^1.6 evaluates to approximately 5.0.
Continuous Compounding and Investment Growth
- Investment of $500 at an annual interest rate of 8.2%, compounded continuously.
- Account value after 15 years: approximately $1,710.61.
