Which function has a vertex at the origin? O AX) = (x+4)
O fx) = x(x-4)
O f() = (x2 - 4)(x + 4)

First of all, to find how much water can the tub hold like finding the volume of the tube, and the tube is a rectangular prism, so we have the volume of it equal length × width × height. So we just need to put the information in here which V= 5×3 1/2×4 1/4=74.375 cubic feet. As a result, the tube could hold 74.375 cubic feet water.
