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!
"Increasing" and "decreasing" are references to what the y-values do when the x-values increase.
Attached is a copy of all four tables, marked with whether the y-values increased or decreased on each step (and it also shows how much that increase or decrease was.
The only table that does this is the top right table in the attachment, which is your second table.
