Choose a real-life situation for the constraints. The function gives at least one negative number as an output. The domain is discrete.
A. the number of ice cream cones purchased as a function of the day of the year
B. the profit (or loss) from the sale of items as a function of the number of items sold
C. the freezing point in degrees Celsius of water as a function of salt content
D. the speed of an airplane as a function of time spent flying

step-by-step explanation:

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'.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
