I argued it too ^_^ (didn't get the points back, though)

Best I can figure is that the function applies to the funciton directly to it's right, In this case, that means f(x) = x^2, and g(x) = mx^2 so this is cos f(g(x))

This may not be what the problem is, IDK, but since the OP doesn't include the answer, I figured it could be, since I've experienced similar frustration in the past.
