Quizplus · Accepted Answer

The solution to $\sin 4x = x$ involves finding the intersection points of the graph of $y = \sin 4x$ and $y = x$. Using a graphing device or software, you can visually determine these points. The correct solutions, accurate to two decimal places, are $0$ and $\pm 0.62$, which correspond to the points where the two graphs intersect.
