# How do you find the domain and range of #y=3x^2#?

##### 1 Answer

For the given function:

**Domain :**

**Range :**

#### Explanation:

Consider the function given:

Create a **data table** as shown:

**Parent** function and the given function.

When we graph, it will help to understand the presence of a numeric value as the **coefficient of the #x^2# term** and its influence on the

**shape of the graph**.

The **Domain** of a function is all possible input values that are used to manipulate to produce an output or result.

The function must also be defined for these values.

For the given function **no constraints** for the

Hence,

**Domain :**

**Range** refers to the set of

Hence,

**Range :**

Examine the graph to visually verify, the results obtained for **domain** and **range**.

Note that the graph for the **Parent function**
