You can put this solution on YOUR website! how can I solve y = log 3 (x- 1)?
---
The question looks like . Evalute the log equation for 3 values of x are greater than 2, three values of x that are between 1 and 2 and x=2. Solve and plot graph?
------
If x = 4, then y = log3(4-1) = log3(3) = 1
If x = 10, then y = log3(10-1) = log3(9) = 2
If x = 28, then y = log3(28-1) = log3(27) = 3
----------------------------
If x = 2, then y = log3(2) = [log(2)/log(3)] = 0.6309
-------
If x = 4/3, then y = log3((4/3)-1) = log3(1/3) = -1
If x = 10/9, then y = log3((10/9-1 = log3(1/9) = -2
If x = 28/27, then y = log3((28/27)= log3(1/27) = -3
---------------------
