Determine if two given function are inverse of each other.

Yes, they are inverse functions.

Step-by-step explanation:

To determine if two functions are inverses of one another, put one in for the x in the other. If the result is f(x) = x, then they are inverses.

f(x) =

f(x) =

f(x) =

f(x) = x

So therefore, they are inverse of each other.

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
