What is the average rate of change of f(x) from 1 to 4?

Help???

Average rate of change

Step-by-step explanation:

To calculate an average rate of change of a function over a range can be calculated as the slope of the the secant line between the two points that defined the range (see figure attached).

The slope can be expressed as:

where a and b are the limits of the range in which we want to calculate the average rate of change.

In this case, for f(x) from 1 to 4 is:

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'.

50-38=12
