y = 0.3x

You can put this solution on YOUR website!
y = 0.3x is defined for all values of x.
So the domain is (-infinity,infinity).

The inverse function (y expressed in terms of x) is x = y%2F0.3 or x+=+10y%2F3.
Here also, x is defined for all values of y.
Hence, the range is (-infinity,infinity).

The graph is given below.
