i'm asked to find the domain of these problems
y= square root x+4
I know with fun. the domain is all IR, but is there a way to solve the problems?
For the domain is
since those are the first elements of the ordered pairs
we can input anything for x here. this is a polynomial, and so, the domain is given by:
For we have a restriction. we can only input the x-values that ensure that what is being square rooted is non-negative. thus we require
so what is the domain of the function here?
