What is the inverse function of f(x)= x/x-2?

The inverse of the function f(x)= x/x-2 is; f-¹(x) = 2x/(x-1)

Since the function can be rewritten as;

By making x the subject of the function;

By swapping x and y; we then have;

The inverse function is therefore; f-¹(x) = 2x/(x-1)

Step-by-step explanation:

Start by replacing f(x) by the variable "y" and solving for x in the equation:

Now do the final replacement using the inverse function notation, and replacing "y" with "x":

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
