Derivative Assignment
Well here is my derivative assignment finally being posted up on the blog. 
For the answers to my derivative question, I will create a comment on this very post detailing the answers for my derivative question.

Derivative assignment
Here are the answers:...
here they come....
should be soon...
ok so the red graph is the original, the green graph is the first derivative and the teal graph is the second derivative. The purple graph is unrelated.

Exponential Functions Lab: Team Sandy/Robert/Aichelle
Hello,
Our group consisted of Sandy, Robert and me, Aichelle.
For question one, we came up with:
similar---> both have inverses.
different---> linear functions have a common difference; exponential functions have a common ratio.
For question two, we said the y-int. was 3 and the growth factor was 4.
We found the value of a to be six in question three.
We know this because:
we were given: f(x) = a ^ x and f(1)=6
so that means a ^ x = 6
and if x = 1
then, a ^ x = a ^ 1
a ^ 1 = 6
or
a ^ 1= 6 ^ 1
since they have the same exponent [1] we can say a = 6.
We said the graph is less than one because the graph is decreasing. As the x-value increases, the y-value decreases. Therefore, a has to be less than 1 in order for that to occur.
For question five we came up with an equation of f(x) = 2 * 5 ^ x.
And lastly, for question 6, we said that the salmonella bacteria growth that doubles every six hours is equivalent to a sixteen fold increase each day because:
there are 24 hours in a day and it takes 6 hours for the bacteria to double.
24hrs/6 hrs = 4 times the bacteria doubles in a day.
since it is doubling we must square how many times in doubles in a day.
4² = 16 times or 16 folds in a day.
Thanks...
