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

question 17

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 $\sum _ { k = 1 } ^ { 4 } f \left( q _ { k } \right) \Delta x _ { k }$ , using the indicated point in the kth subinterval for $c _ { k }$ .
- $f(x) =2 x+1,[0,2], \text { left-hand endpoint }$
