Given the data

x	y
1	0
2	4
3	6.5
4	8
5	9

Develop a least squares logarithmic model and use 4 place accuracy after the decimal point.

A) What is the model and what is

R2

?

B) Use the model to find the rate of change when x=5. Please show the work to get answer.

C) Using the model, x needs to be solved when y=10. Please show the analytic work which would be great.
