{(3, -5): (8, -6),
(3. 7). (5.9))
Is it a function?
Domain
(c) Range:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.

step-by-step explanation:

any linear relation with finite slope (that is, something other than x=constant) will be a function with a domain and range of "all real numbers."

further, any odd-degree polynomial will likewise be a function with domain and range of "all real numbers." a linear equation is a polynomial of degree 1, hence of odd degree.
