1. finish 4.4 ws - practice finding exponential models
* the answer to #1 - y = 380.87(3.1876)^x after 3 hours = 12.336
* solutions to #2 and #3 on the 4.4 practice ws - click here!
* the answer to #4 - y = 63.17(.5)^(x/30) after 65 years = 14.07
2. chapter 4.4 quiz - finding exponential models! let's make it 2 problems (maybe one growth and one decay??) for a total of 16 points.
This could be a great opportunity to give your term 3 grade a little kick...
STEPS:
1. set up two equations y = ab^x (plug in y and x values) - BIGGER EXP ON TOP!
2. divide to cancel a's
3. solve for b by raising both to reciprocal power
4. solve for a by plugging b value into original equation with smaller exponent
5. exponential model y = ab^x with knows values for a and b.
