Question

O POLYNOMIAL AND RATIONAL FUNCTIONSDomain and range from the graph of a quadratic function

Answer 1

Explanation

We are given the following graph:

We are required to determine the domain and range of the given graph.

We know that the domain of a quadratic function is all real numbers.

The range of the function is from the vertex upwards.

Hence, the answers are:

`\begin{gathered} (a)\text{ }range:[2,\infty) \\ (b)\text{ }domain:(-\infty,\infty) \end{gathered}`
