3.1-3.4

3.1-3.4

1. exponential growth and decay: f(x)=Ca^x where a>1

   • x= # of time periods
   • a= growth factor
   • C= initial value
   • Finding the growth or decay factor use: Later/Initial

2. linear: y=mx+b

3. Fractional exponents are the square root

   • ex: 10^1/5 or the 5th root of 10

4. Half-life: (.5) or (1/2)

   • ex: (.5)^1/6 : The half life is 6 hours, find the hourly decay factor

5. compound interest formula: A=P(1+r/n)^n(t)

   • compounding continuously: A=Pe^r(t)
