How do I restrict the domain of yx1to the power of 2Solution

How do I restrict the domain of y=(x+1)to the power of 2?

Solution

To determine the domain of y = (x+1)^2.

Solution:

The set of all possible values of x for which the y values (called image or range of the function) are real is called the domain of the function y = (x+1)^2.

Here for any real value of value of x, the function y = (x+1)^2 is real.

Therefore domain of x is any value in (- infinity , infinity). Or all real values. Or x belongs to R.
