You can put this solution on YOUR website! At what point(s) do the graphs of y=2log(x) and y=log(2x) intersect?
----------------
Substitute to get:
2log(x) = log(2x)
---
log(x^2) = log 2x
------------------------
x^2 = 2x
x^2-2x = 0
x(x-2) = 0
x = 0 or x=2
-----------------------
x cannot be zero because log(2*0) = log(0) does not exist.
-------------------
So, x = 2
---
Then y = log(2x) = log(4) = 0.6021
----
Point of intersection: (2,0.6021)
