The domain of the function will be all real numbers if the function y=4[x+2] for all x belongs to (-∞, +∞).
What is a function?
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 function:
y=4[x+2]
Since the function is not in the fraction form so from the properties of the function, the domain of the function will be all real numbers because x ∈ (-∞, +∞)
Thus, the domain of the function will be all real numbers if the function y=4[x+2] for all x belongs to (-∞, +∞).
