Chapter 3

1. Toolkit A.3 and A.4

   • The toolkit is about exponents and the rules of exponents
     • Example: any exponent to the power of 0 always is answered with 1
       • Any exponents with the same base and is multiplied add the exponents
         • If the same base is present but it is division then subtract the exponents
           • If a power is raised to a power then you multiply the powers
             • No negative exponents can be present if there is one swap its place

2. Section 3.1

   • This section is about exponential growth and decay and how it is applied

3. Section 3.2

   • Exponential Models and the change in time and compound interest
     • The 30-minute growth factor is (a) what is it in 1 hour?
       • a^2
         • Half-life of a radioactive material is h years
           • Its equation is 1/2^(1/h)

4. Section 3.3

   • The difference between linear and exponential functions and growth

5. Section 3.4

   • Graphing exponential formulas and using Ca^t to properly graph them
     • As an example of exponential formulas
       • f is an exponential function with base of 7
         • so as a few examples
           • f(2)=49
             • f(0)=1
               • f(-2)=-49
