Answer:

Domain : ( -∞ , ∞ ) ; range ( -∞ , ∞ ]

Explanation:

Given : y=-3x².

To find : Identify the domain and range .

Solution : We have given that y = -3x².

Domain : the domain of the function is the set of input values for which function is defined .

So, the function is defined for all real values .

Notation : ( -∞ , ∞ )

Range : The set of values of dependent variable for which function is defined .

Range for quadratic function is always less than or equal to 0 .

Notation : ( -∞ , ∞ ]

Therefore , Domain : ( -∞ , ∞ ) ; range ( -∞ , ∞ ]
