Question

Please help me with the 2nd part of this. What is it in interval notation?

Answer 1

Given:

The objective is to find the range of the graph.

Explanation:

The range of a graph represents the lowest point and highest point in the y-axis.

From the graph, the lowest point of the graph touches at -4 and the highest point touches at 5.

Then, the range in interval notation will be,

`\lbrack-4,5\rbrack`

Hence, the range of the graph in interval notation can be represented as [-4,5].
