Question

What is the range of the function

Answer 1

`\ y\;`

Explanation:

The range of a function is the set of all possible output values (y-values).

From inspection of the given graph:

• Minimum value of y = 0
• Maximum value of y = 9

As there is an open circle where y = 9, this means the value is not included in the range.

Therefore, the range of the function is:

`\ y\;`
