- (-infinity,
#<-3# ), U#(>3# , infinity) - (-infinity,
#<2# ), U#(>2# , infinity) - (-infinity,
#<=0)# , U#(>0# , infinity)
Explanation:
#f(x)# =#(sqrt(x+1))/(x^2-9)#
Here, considering denominator,#(x^2-9) #
which becomes zero when#x=+-3# leads us to the value of the function to take infinity.
Hence the domain happens to be,
Set of all real numbers except -3 and +3
(-infinity,#<-3# ), U#(>3# , infinity)
2.
Here, consider the term
Hence, the domain happens to be
Set of all real numbers except 2
(-infinity,
3 In this function the function is not unique at x = 0.
Hence, the domain happens to be set of all real numbers except 0
(-infinity,
