Answer:

Step-by-step explanation:
So, we have the graph y=f(x).
And we want to find:

Remember that the inverse of a function is simply the x-values and y-values swapped. To see this, let's let our inverse equal y:

This means that we have the point:

So, to find our solution, we will swap the x- and y-coordinates. This gives us:
So, simply need to find the x-coordinate such that y is 0.
From our graph, we can see the point (6,0). In other words:

So:

And we're done!
