A car $\"\"$ s speedometer reads $\"\"$ an hour.

a.The difference between the car $\"\"$ s actual speed $\"\"$ and the reading on the speedometer.

Write an absolute value function.

The function is $\"\"$ .

$\"\"$

b.Find an appropriate domain for the function.

Since the speed of the car cannot be negative.

The appropriate domain for the function is $\"\"$ .

$\"\"$

Graph:

Graph of the function is $\"\"$ .

Observe the graph:

Domain is set of all real numbers greater than $\"\"$ .

Range is all real numbers.
