Give the domain and range of the function. Tell whether the relation is a function.

The domain is [0,4], as the x-values go from 0 to 4.

The range is [0,4], as the y-values span from 0 to 4.

The relation is a function

- For a relation to be a function, each x-value can have only one, distinct y-value. This is the case for this relation, as each x-input has only one corresponding y output.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
