question 70

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 $c _ { k }$ .
- $f(x) =x^{2}-2,[0,8], \text { midpoint }$
