Consider this graph of the function here.
00:02
We are to find the following values.
00:04
First one is the value of the inverse of this function at negative 4.
00:10
Now remember that if y equals f of x, then x is equal to f inverse of y.
00:23
Meaning, when we're looking for the value of the inverse, we're looking for the x value given a specific y value.
00:31
So for this, the y value is negative 4.
00:36
So we're looking for the x value when y is negative 4, and that's going to be 0.
00:46
So this inverse is equal to 0.
00:49
And then we have f inverse of negative 3.
00:54
So the y value is negative 3.
00:58
1, 2, 3, it's over here, and the x value is negative...
