Question

A rain gauge is used to measure the

rainfall overnight. The function
f(x) = 0.2x can be used to model the
inches of rain per hour for a total of 6
hours.
X represents:
Y: represents: i
Domain:
Range:
I

Answer 1

Explanation:

x represents the hours of rain (0 to 6).

y (= f(x)) represents the inches of rain fallen during the given hours.

the domain is the interval or set of the valid x-values. in our case [0 .. 6].

the range is the interval or set of the valid y-values. in our case that is [0×0.2 .. 6×0.2] = [0 .. 1.2]

Answer 2

X represents the number of hours.

Y represents the inches of rain per hour.

Domain: The possible values for x, which is the number of hours, would typically be a non-negative integer since you can't have a negative or fractional number of hours.

Range: The possible values for y, which is the inches of rain per hour, would be any non-negative real number since rainfall can be measured in fractions of an inch.
