Answer:

Domain of f(x): All real values.
Range of f(x): All real values.
Domain of f -1(x): All real values.
Range of f -1(x): All real values
Step-by-step explanation:
We are given the following function:

Since it is a line, we have that both the domain is the range is the real set.
Inverse function:
The domain of the inverse function is the range of the original function, and the range of the inverse function is the domain of the original function.
Finding the inverse function:
Exchange x and y in the original function, and isolate y. So
Original

Exchanging:

Isolating y:



He went upstream 3 hours and downstream two. 4x3=12 6x2=12
He went 24 miles.
512, the formula for volume is length x width x height :)
To find the unit rate, all we need to do is divide $22.68 by 12
22.68 ÷ 12 = 1.89
Therefore, each gallon of gas costs $1.89
