Question

Write the range of the function using interval notation.

Answer 1

Given:

The graph of a function.

To find:

The range of the given function using interval notation.

Solution:

Range: The set of y-values or output values are known as range.

From the given graph, it is clear that the function is defined for
`0<x<4` and the values of the functions lie between -2 and 2, where -2 is excluded and 2 is included.

Range
`=\y`

The interval notation is:

Range
`=(-2,2]`

Therefore, the range of the given function is (-2,2].
