Question

2. X 0 4 7 10 13 y -5 -5 -5 -5 -5 Domain: ______________________ Range: _______________________ Function? _______

Answer 1

`Domain =\{0,4,7,10,13\}`

`Range = \{-5\}`

`y = -5` --- function

Explanation:

Given

`\begin{array}{cccccc}x & {0} & {4} & {7} & {10} & {13} \ \\ y & {-5} & {-5} & {-5} & {-5} & {-5} \ \end{array}`

Solving (a): The domain

The x values represent the domain.

Hence, the domain is:

`Domain =\{0,4,7,10,13\}`

Solving (b): The range

The y values represent the range

Hence, the range is:

`Range = \{-5\}`

Solving (c): The function

By observation, we can see that for all values of x the value of y remains unchanged (-5)

Hence, the function is:

`y = -5`
