Let `f(x)={x^n, x` is rational and ` -x^n, x` is irrational then `f(x)` is discontinuous at `x = 0` if n

If f(x)={x^(2) if x is rational and 0, if x is irrational }, then

f(x)={x if x is rational -x if x is irrational then Lt_(x rarr0)f(x)=

Let f(x)=x^2 if x is rational and f(x)=1-x^2 if x is irrational then the number of points of continuity of f is

Let f(x)=[x^(2) if x is irrational,1 if x is rational then

Let f(x)=0 for x is rational and x if x is irrational and g(x)=0 if x is irrational and x if x is rational then the function (f-g)x is

Let f(x)=[0, if x is rational and x if x is irrational and g(x)=[0, if x is irrational and x if x is rational then the function (f-g)x is

Let f(x) = {(x", if x is irrational"),(0", if x is ratinal"):} then f is

Let f(x) = [{:(x^(2), " if x is irrational"),(1, " if x is rational"):} , then

Show that the function f defined by f(x)={(1 if "x is rational"),(0if "x is irrational"):} is discontinuous AAne0inalpha
