Answer:
Explanation:
Given is a function as
We find that this funciton is undefined for denominator =0
Denominator =0 when
Hence function is not defined for x=1,-1
Domain is R-{-1,1}
To find range:
We see that denominator has degree 2 and numerator degree 1
i.e. denominator has more degree of x then numerator
Hence y=0 is horizontal asymptote
But when y=0 we have x=0
Hence though there is a horizontal asymptote range is the set of all real numbers
Domain = R-{-1,1}
Range = R
