Chapter EP, Problem 2.1.1EP

To determine

To Find: The domain and the range of each relation, then determine if the relation is function and determine if the function is one to one, onto, both or neither.

Answer to Problem 2.1.1EP

Thedomain is $\left(1970,1980,1990,2000\right)$ and the range is $\left(13468,11605,15630,18140\right)$ . Thedomain is paired with one number of the range so the relation is not the function.

Explanation of Solution

Given:

Thegiven points are $\left(1970,11605\right),\left(1980,13468\right),\left(1990,15630\right),\left(2000,18140\right)$ .

Calculation:

Consider the points are $\left(1970,11605\right),\left(1980,13468\right),\left(1990,15630\right),\left(2000,18140\right)$ .

The domain of the equation is,

  $\left(1970,1980,1990,2000\right)$

The range of the equation is,

  $\left(13468,11605,15630,18140\right)$

The domain is paired with one number of the range so the relation isnot the function.
