To graph an inverse variation function, typically represented as ( y = \frac{k}{x} ) (where ( k ) is a constant), start by plotting key points based on values of ( x ) and calculating corresponding ( y ) values. The graph will consist of two distinct branches in the first and third quadrants (if ( k > 0 )) or in the second and fourth quadrants (if ( k < 0 )). As ( x ) approaches zero, the values of ( y ) will increase or decrease towards infinity, creating asymptotes along the axes. Finally, connect the points smoothly to form the hyperbolic shape characteristic of inverse variations.
To graph the inverse of a function without finding ordered pairs, you can reflect the original graph across the line ( y = x ). This is because the coordinates of the inverse function are the swapped coordinates of the original function. Thus, for every point ( (a, b) ) on the original graph, the point ( (b, a) ) will be on the graph of its inverse. Ensure that the original function is one-to-one for the inverse to be valid.

In general the function and it inverse are not the same and do not have the same graph. If we look at a special function f(x)=x, it is equal to its inverse and the graph is the same. Think of the inverse of a function as changing all the x's to y's and vice versa. Well, in the function f(x)=x, all the x's are already y's and vice versa so it is its own invese.
The graph of the function y(x) = 1/x is a hyperbola.

Inverse variation does not pass through the origin, however direct variation always passes through the origin.

The relationship between a logarithmic function and its graph is that the graph of a logarithmic function is the inverse of an exponential function. This means that the logarithmic function "undoes" the exponential function, and the graph of the logarithmic function reflects this inverse relationship.
