Okay, so here we have square root function.
00:03
So as we know, to find a square root of any number, that number should be positive, right? so here, 5 plus 8x should be positive and 0, right? so here, 8x is greater than or equal to negative 5.
00:22
So here, x should be greater than or equal to negative 5 by 8, right? that is the domain of our given function.
00:30
Now to find the inverse function we need to interchange the variable and solve for y.
00:36
So here by interchange the variable, we have x is equal to square root of 5 plus 8 y.
00:51
And here, y should be greater than or equal to negative 5 by 8.
00:56
Right...
