Use the Left and Right Riemann Sums with 4 rectangles to estimate the (signed) area under the curve of \( y=\sqrt[3]{x-1} \) on the interval of \( [3,7] \). Round your answers to the second decimal place. Left Riemann Sum \( = \) Tries 0/99 Right Riemann Sum \( = \) Tries 0/99 Use the Left and Right Riemann Sums with 100 rectangles to estimate the (signed) area under the curve of \( y=-8 x+7 \) on the interval \( [0,50] \). Write your answer using the sigma notation. Left Riemann Sum \( =\sum_{i=0}^{99}( \) Tries \( 0 / 99 \) Right Riemann Sum \( =\sum_{i=1}^{100}(\quad) \) Tries \( 0 / 99 \)
