Graph the function and identify the domain and range y=-3x^2

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

Step-by-step 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 ( -∞ , ∞ ]

the answer is c: divide the arc's degree measure by 360°, then multiply by the circumference of the circle.
