what is the domain of function

f(x)= (√(x+a²) - a)/x a>o

f(x)=(√(x+a²) - a)/x

x cant be 0 bcz in that case this function will not defined……..(1)

part the function inside under root should be positive

(x+(a)^2)>0  since ‘a’  is constant quantity so x> -a^(2)………….(2)

From (1) and (2) we get domain of x belongs to

[-a^(2),+infinity)-[0]
