Answer:
Step-by-step explanation:
The range of a function is the set of all possible values it can produce.
For example, consider the function
No matter what value we give to x, the function is always positive:
If x is 2, then the function returns x squared or 4.
If x is negative 2, then it still produces 4 since -2 times -2 is positive 4.
So the range of the function is
"all real numbers greater than or equal to zero".
