Jose is the water maintenance supervisor for his city. he knows the rate rainwater flows through a pipe is modeled by the equation r(x)= -0.1x^3+1.4x^2-1.5x, where r is the amount of water, in cubic feet, and x is time, in hours. jose a developer of a new neighborhood that if she decreases the size of the pipe, the water flow will decrease. the function that models the decrease is d(x)-0.04x^3+0.5x^2+x, where d is the amount of water in cubic feet, and x is time, in hours.
write a function, h(x), for the rate at which rainwater flows in the smaller pipe.
