The diagram shows part of the graph of $$\(y=a \cos (b x)+c\)$$. For these values of $$\(a, b\)$$ and $$\(c\)$$, use the given diagram to determine the number of solutions in the interval $$\(0 \leqslant x \leqslant 2 \pi\)$$ for each of the following equations. $$\(a \cos (b x)+c=6-\frac{6}{\pi} x\)$$ ............................................................................................................................................ ............................................................................................................................................
