If `f: R->R` is defined by `f(x)={(x+2)/(x^2+3x+2) if x in R-{-1,-2}, -1 if x = -2 and 0 if x=-1. ifx=-2` then is continuous on the set

If f : R to R is defined by f (x) = {:{((x+2)/(x^(2)+3x+2), if x in R - { 1,-2}), ( -1, if x = -2) , ( 0 , if x = -1 ) :} then f is continuous on the set

If f: RR to RR is defined by f(x)={{:(,(x+2)/(x^(2)+3x+2),"if "x in R-{-1,-2}),(,-1,"if "x=-2),(,1,"if "x=-1):} then is a continuous on the set

If f : R rarr R is defined by f(x) = {((x+2)/(x^(2)+3x+2), x in R-{-1,-2}),(-1, x=-2),(0, x = -1):} then f is continuous on the set

If f: R rarr R is defined by f(x)=(x)/(x^(2)+1) find f(f(2))

If f: R to R is defined by f(x)=(x^(2)-4)/(x^(2)+1) , then f(x) is

If f:R rarr R is defined by f(x)=x/(x^2+1) find f(f(2))

If f :R to R is defined by f (x) =(x )/(x ^(2) +1), find f (f(2))

If f : R to R is defined by f(x) = x/(x^(2)+1) find f(f(2)) .
