The funcion `f(x)=(|x-3|)/(x-3)` at `x=3,` is

The function f(x)=x^(3)-3x is

The function f(x)=x^(3)-3x is

The function f(x)=x^(3)-3x is :

The fucntion f(x) =x^3-3x, is

The function f(x) = x^(3) - 3x is ……..

If the function f(x)={{:((x ^(2) -9)/(x-3), "when" x ne3),(2x+a, "when" x=3):} is such that lim _(x to3) f(x) =f(3), then the value of a is-

f(x) =3x +(1)/(3x)

The range of f(x) = ( x-3)/( 3-x), x ne 3 is
