The domain of the function is all real numbers, the range of a function is y ≤ 4
It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have a function:
f(x) = –(x + 6)(x + 2)
If we plot this function on the coordinate plane, we will see it is a graph of a quadratic function.
Here the no other details are given.
But we can say:
Thus, the domain of the function is all real numbers, the range of a function is y ≤ 4
