Part 1
-9
---------------------------
Explanation:
Let's focus on evaluating first. We need to look at the table and locate f(x) = 13. So we're looking in the f(x) row where 13 shows up. That's in the second to last column. Right above that we have x = 5
This means f(5) = 13 and The inverse undoes the f(x) function. So the input x and output y values swap places. This is why we're reading the table in reverse.
We can replace all of with 5 to go from to
Then we repeat the process of using the table. Locate 5 in the f(x) row. This is in the last column. The value above that is x = -9.
So f(-9) = 5 and
Overall,
===============================================
Part 2
-13
---------------------------
Explanation:
Same idea as before. Locate 8 in the f(x) row. The value above this is x = -13
This means f(-13) = 8 and
f⁻¹(-2) = 3 and f⁻¹(1) = 0.
Step-by-step explanation:
By the definition of inverse functions:
From the table, note that f(3) = -2.
Then by definition, f⁻¹(-2) = 3.
Likewise, f(0) = 1.
Then by definition, f⁻¹(1) = 0.
Invertible functions are functions whose inverse can be calculated.
The values of the expressions are: and
The table entry is given as:
x | 5 | 3 | 1 | 18 | 0 | 9
f(x) | 9 | -2 | -5 | -1 | 1 | 11
(a) Calculate f^-1(f(5))
Start by calculating f(5).
From the table, we have:
Take inverse function of both sides
From the table, the inverse value of 9 is 5.
i.e.
So, we have:
(b) Calculate f(f(5))
In (a) above, as have:
So, the function becomes
From the table, the value of f(9) is 11.
So, we have:

Step-by-step explanation:
The given table :
x: -14,-7,-12,9,10,-2
f(x):11,-12,5,1,-2,13
Since f is invertible ( given) , then exists.
Now , from table [ x= 9 corresponding to f(x) =1]
[ f(x) = 11 corresponding to x=-14]
then,
So,
Also, x= 10 corresponding to f(x) =-2, then
( 1 ) ,
( 2 )
Step-by-step explanation:
Taking the function and it's inverse, it should be the following property -
- this therefore makes the functionality " " equivalent to 576 itself.
For this second part here let's consider the portion " " firstly. As you can see from the table, - 7 should represent the x - value, hence . Now for this second bit here, we have to take the inverse - making the what should have been the x - value, now the f( x ) value. Therefore, .
This would make = = 13.
Step-by-step explanation:
Given
The attached table
This represents an inverse function.
So, we look into x row for its value.
i.e.
Just like (a)
---- by looking into the x rows
So:
Answer for the first box = 10
Answer for the second box = -10
======================================================
Work Shown:
f(x) is a function where we plug in the given row of x values to have them lead to the corresponding f(x) values in the table. We see that x = 14 leads to y = f(x) = 7. Going backwards, we can say . The inverse simply undoes everything f(x) does.
So,
For the portion , look at the column that has x = 10. This shows it leading to f(x) = 14. You trace this column upward to go backward to undo f(x).
------------------------------
That takes care of the first part. The second part is pretty much the same idea. We locate where -4 is in the bottom row, and then we write down the corresponding x value.
We see that y = -4 pairs with x = -10, which is why
-----------------------------
Keep in mind that this function must be one-to-one for the inverse to exist. If not, then you'll have to do some kind of domain restriction.
The value of is 3
The value of is 18
Explanation:
Given that the set of inputs and outputs of the invertible function f.
We need to determine the values of and
The value of :
We need to determine the image of the y - value -2.
The image of the y - value (-2) is the corresponding x - value from the given table.
Thus, from the table, the image of -2 is 3.
Hence, the value of is 3.
The value of :
We need to determine the image of the y - value -1.
The image of the y - value (-1) is the corresponding x - value from the given table.
Thus, from the table, the image of -1 is 18
Hence, the value of is 18.
f⁻¹(-2) = 3 and f⁻¹(1) = 0.
Step-by-step explanation:
By the definition of inverse functions:
From the table, note that f(3) = -2.
Then by definition, f⁻¹(-2) = 3.
Likewise, f(0) = 1.
Then by definition, f⁻¹(1) = 0.
Step-by-step explanation:
