hello, my question is:
how many times does the graph of y=0.1x intersect the graph of y=sin(2x)?
thanks!

See the first graph below.

The problem is those two outer points. Are the intersections or not? The answer is "no" because if you blow one of those areas up you get the second graph.

So ThePerfectHacker is correct, there are 11 intersections.
