a) Sketch the graph of $\displaystyle y=|2cosx|+1$ for 0 ≤ x ≤ 2$\displaystyle \pi$, stating the coordinates of the turning points.

b) State the number of solutions for the equation $\displaystyle |2cosx|+1 = \frac{x}{2}$ for 0 ≤ x ≤ 2$\displaystyle \pi$

I have already solved for part a, having problems with part b...

I am guessing that we have to equate $\displaystyle y=\frac{x}{2}$
