Answer:

The domain of the relation is $D = [-2,\infty)$

The range of the relation is $R = (-\infty, \infty)$

Step-by-step explanation:

Domain and range:

Domain is considered to be the input values, in a graph, the values of x.

Range is considered to be the output values, in a graph, the values of y.

In this graph:

x starts at -2 and goes to infty. So the domain is: $D = [-2,\infty)$

As for y, the arrows indicates it goes to infinity. So $R = (-\infty, \infty)$

What is the work to find out the awnser to find out how many centimeters in a foot

igor_vitrenko [27]

To find how many cm are in a ft, you have to use the method of unit rate:

so we know that 12 in. equals a ft. so,

1 ft
------
12 in.

and 2.25 cm equals an in. so,

1 in.
-------
2.54cm

then we put the rates together and get:

1ft 1 in.
---- X -------................we cancel out the in. units and get:
12 in. 2.54 cm

Solve and get 1 ft = 30.48 cm
