Question

Whats the inverse of f(x)= 2x-3

Answer 1

We have

`f(x)=2x-3​`

We have

y=2x+3

We replace x with y

x=2y-3

then we isolate the y and we obtain the inverse function is

`(x+3)/(2)`

The domain is the set of all possible values that can have x , the domain of the inverse function is

`(-\infty,\infty)`

the range is the ser of values that can have y all the possible values in this case the range is

`(-\infty,\infty)`
