Identify the domain of the function shown in the graph.

The correct option is D) x is all real numbers.

Step-by-step explanation:

Consider the provided graph.

The provided graph is a horizontal line parallel to x axis.

where the equation of the graph is y=-3

The domain of a function is the set of all x values which a function can take.

Here, we can see that for every value of x the function gives the constant value which is -3.

Thus, the function is continuous at everywhere.

Therefore the domain of the function is all real number.

Hence, the correct option is D) x is all real numbers.

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
