The function `f(x)=(7)/(x)-3, x in R, x ne 0` is

The function f(x)=x-(1)/(x), x in R, x ne 0 is

The function f(x) = x-1/x, x in R, x ne 0 is increasing

The function f(x)=(3)/(x)+10, x ne 0 is

Prove that functions f(x) = x -(1)/(x) ,x in R and x ne 0 is increasing functions.

What is the range of the function f(x)=(|x|)/(x), x ne 0?

Let the function f(x)=x^(2)sin((1)/(x)), AA x ne 0 is continuous at x = 0. Then, the vaue of the function at x = 0 is

The function f(x) = 3/x + 10, x ne 0 is decreasing

Function f(x)=7x-3 defined in R is a/an

Show that the function f(x)=(3)/(x)+7 is decreasing for x in R-{0}

If R is the set of real numbers then prove that a function f: R to R defined as f(x)=(1)/(x), x ne 0, x in R, is one-one onto.
