Answer:
domain is ( -∞ ,∞), Range is ( -∞ ,1 ].
Explanation:
Given : The graph of the function f(x) = -(x+3) (x-1).
To find : domain and range of the function.
Solution : We have given that f(x) = - (x+3) (x-1).
Domain : The domain is the set of input values of x for which function is real and defined.
Since, domain is ( -∞ ,∞).
Range : The range is set of dependent values for which function is defined.
Range : ( -∞ ,1 ].
Therefore, domain is ( -∞ ,∞), Range is ( -∞ ,1 ].
