I hate math, and suck at it, but I have to do it. I'm stuck on only one question on my current assignment. It looks really simple, but I've tried it a couple different ways, and I end up hitting a brick wall. Here it is;

I haven't been able to find a value for x, and if it doesn't have a solution, I'm not sure how to show that... Can anyone help?2. Does the equation 3x^3 - sin(x) + 3 = 0 have a solution?

We've been mostly dealing with limits so far, so this question kind of threw me for a loop. I'm not sure how to isolate x...
