Answer:
- f⁻¹(k) = k/1.609344
- f⁻¹(k) is the exact number of miles in k kilometers
Step-by-step explanation:
(a) If we let k = f(m), we can solve for m to find f⁻¹(k).
k = 1.609344m
k/1.609344 = m = f⁻¹(k)
__
(b) Since k is the number of kilometers in m miles, m is the number of miles in k kilometers.
__
In summary ...
(a) f⁻¹(k) = k/1.609344
(b) f⁻¹(k) is the exact number of miles in k kilometers
