Question

i solved a function f(x)=2x+3
and got my inverse function as (x-3)/2
what will be my domain and range? i solved a function f(x)=2x+3
and got my inverse function as (x-3)/2
what will be my domain and range? @Mathematics

Answer 1

Your function was from R -> R.
So the inverse function is still from R-> R

The inverse function swaps domain with co domain

Answer 2

explain better pls

Answer 3

All right. First above all, your starting function was:

y = 2x+3
Which is a line, we know about the domain to be R and the co-domain to be R
So R->R

Now, the inverse function is:

x = (y-3)/2

Now, your initial function CO-domain will become the domain of the inverse function, so it'll still be from

R-> R
