Graph the Function $f ( x )$ Over the Given Interval $\sum _ { k = 1 } ^ { 4 } f \left( c _ { k } \right) \Delta x _ { k }$

question 273

Multiple Choice

Graph the function $f ( x )$ over the given interval. 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 indicated point in the kth subinterval for $\mathrm { c } _ { \mathrm { k } }$ .
- $f ( x ) = \cos x + 1 , [ 0,2 \pi ]$ , left-hand endpoint
