Question

what is the domain of Y = √x+2​

Answer 1

Answer:

put y equal to any integer the value you get is domain that is value of y is considered as a domain so try to find it out by putting integeres in place of x and y as we did in finding coordinates of graph !

Answer 2

Domain = [0, infinity)

step by step explanation:

We will restrict our discussion in

R.

As we can not find the square root of

x<0,x≥0

So, the Domain is the set of all non-negative reals, i.e.,

R+∪{0}=[0, infinity).
