Hope this helps I can't write the process
Answer:
f⁻¹(-2) = 3 and f⁻¹(1) = 0.
Step-by-step explanation:
By the definition of inverse functions:
![\displaystyle \text{If } f(a) = b\text{, then } f^{-1}(b) = a](https://tex.z-dn.net/?f=%5Cdisplaystyle%20%5Ctext%7BIf%20%7D%20f%28a%29%20%3D%20b%5Ctext%7B%2C%20then%20%7D%20f%5E%7B-1%7D%28b%29%20%3D%20a)
From the table, note that f(3) = -2.
Then by definition, f⁻¹(-2) = 3.
Likewise, f(0) = 1.
Then by definition, f⁻¹(1) = 0.
Round the numbers to the nearest ten thousand:
63,000 km & 20,000 km
Then find the difference (subtract):
63,000 km - 20,000 km = 43,000 km
Don't forget to put the unit of measurement on there (km)
Hope this helps :)
