मान लीजिए कि `f={(x,(x^(2))/(1+x^(2))),:x in R}R` से R में एक फलन है । f का परिसर निर्धारित कीजिए

f={(x,(x^(2))/(1+x^(2))):x in R} be a function from R into R. Determine the rage of f .

f:R rarr R defined by f(x)=(x)/(x^(2)+1),AA x in R is

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

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

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

f : R to R : f (x) =x^(2) is

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+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,f(x)=x^(2), then {x|f(x)=-1} equals
