Find any inflection points of f . Select the correct choice below and, if necessary, fill in the answer box to complete your choice. (D). The function has an inflection point at \( (0,6) \). (Type an ordered pair, using integers or fractions. Use a comma to separate answers as needed.) B. The function f has no inflection points.

Suppose the interval \( [-5,-3] \) is partitioned into \( n=4 \) subintervals. What is the subinterval length \( \Delta x \) ? List the grid points \( x_{0}, x_{1}, x_{2}, x_{3}, x_{4} \) Which points are used for the left right, and midpoint Riemann sums? \( \Delta x=\square \)

2. \( \int_{2}^{2}\left(5 x^{2}+3 x+5\right) \cdot d x=\left({ }_{2}^{3}\left(5 x^{2}+8 x+5\right) d x\right. \) 3. \( \int_{2}^{3}\left(x^{3}+9\right) \cdot d x= \)

Encuentre el volumen del solido que está debajo del paraboloide elíptico \( \frac{x^{2}}{4}+\frac{y^{2}}{9}+z=1 \) y arriba del rectángulo \( R=[-1,1] \times[-2,2] \)

\( \frac{d}{dx}(y^{3}\sqrt {x^{2}+y})=\frac{d}{dx}(x) \)

\( \lim _ { x - 6 } \frac { x ^ { 2 } - 36 } { 4 x ^ { 2 } - 16 x - 48 } \)
