Graph the function \( f(x)=\cos x+4 \) over the interval \( [0,2 \pi] \). Partition the interval into 4 subintervals of equal length. Then add to your sketch the rectangles associated with the Riemann sum \( \sum_{k=1}^{4} f\left(c_{k}\right) \Delta x_{k} \), using the right endpoint in the kth subinterval for \( c_{k} \). A. B. C.
