A relation is given by the set of ordered pairs: R = (-2, 3), (-1, 4), (1, 7), (2, 7). Write down the domain and range of R.

Here are the solutions to problems 6 and 7.

:
A relation is given by the set of ordered pairs: $R = \{(-2, 3), (-1, 4), (1, 7), (2, 7)\}$.

a) To write down the domain and range of R.

Step 1: Identify the domain. The domain is the set of all first elements (x-coordinates) from the ordered pairs.

$$\text{Domain} = \{-2, -1, 1, 2\}$$

Step 2: Identify the range. The range is the set of all second elements (y-coordinates) from the ordered pairs.
