The volume of water in Tank \( P \) is less than that in Tank \( R \). The volume of water in Tank \( Q \) is greater than that in Tank S.

Question 16 The polynomial function \( f \) is defined by \( f(x)=-3 x^{4}-7 x^{3}+3 x^{2}+9 x-1 \). Use the ALEKS graphing calculator to find all the points \( (x, f(x)) \) where there is a local minimum. Round to the nearest hundredth. If there is more than one point, enter them using the "and" button. \( (x, f(x))=\left(\prod_{1}, \square\right) \)

a) \( \mathrm{F}(\mathrm{A}, \mathrm{B}, \mathrm{C}, \mathrm{D})=\sum(0,1,2.3,4,6,7,8,9,10,15) \) b) \( \mathrm{F}(\mathrm{A}, \mathrm{B}, \mathrm{C}, \mathrm{D})=\sum(0,4,6,8,9,11,11,14,15) \)

Choose the two equivalent expressions.
