9. The function M(d) below relates the distance (measured in miles) Bob can
drive his rental car and the amount of
money (in dollars) it will cost.
It takes as input the number of dollars
spent and returns as output the
number of miles driven.
M(C) = 40(0 - 35)
Write the equation that represents the
inverse function D(m), which takes
the number of miles driven as input
and returns the number of dollars
owed.
