Answer: The correct answers are:
- f^{-1}(-2)=3
- f^{-1}(1)=0
Step-by-step explanation:
* Since f^{-1} receives inputs from f's range and maps them to their corresponding elements in f's domain, we can reverse the rows in the table as follows to obtain the inputs and outputs of f^{-1}.
* From this table we see that f^{-1}(-2)=3 and that f^{-1}(1)=0.
* Therefore, the correct answers aref^{-1}(-2)=3 and f^{-1}(1)=0
The required values f⁻¹(-2) = 3, f⁻¹(-1) = 18, obtained by swapping the input and output values in the inverted table.
To find the inverse of the function, can swap the input and output values in the given table.
Then, you can use this inverted table to find the values of the inverse function for specific inputs.
As per the table values are,
x | 5 | 3 | 1 | 18 | 0 | 9
f(x) | 9 | -2 | -5 |-1 | 1 | 11
The values in the inverted table are,
f⁻¹(x) | 9 | -2 | -5 |-1 | 1 | 11
x | 5 | 3 | 1 | 18 | 0 | 9
Now, to find the values of the inverse function:
f⁻¹(-2): Looking at the inverted table, when f⁻¹(x) = -2, the corresponding input x is 3. Therefore, f⁻¹(-2) = 3.
f⁻¹(-1): Similarly, when f⁻¹(x) = -1, the corresponding input x is 18. Therefore, f⁻¹(-1) = 18.
Therefore, the values in the inverted table are f⁻¹(-2) = 3 and f⁻¹(-1) = 18 .

Answer:
3.1 = 3.10 because adding zero (0) in decimal number at the right most side doesn't affect the number as the same way adding zero at the left most side of a number doesn't affect the number.
Also, 3 and 1 ones are the same as 3 and 10 tenths.
Answer:
25%
Step-by-step explanation:
Initial hourly pay of Mario = $8
Current hourly pay of Mario = $10
Increment = current hourly pay - initial hourly pay = $10-$8 = $2
% increase in hourly pay rate = increment/initial pay × 100$
℅ increase = $2/$8×100%
% increase = 1/4×100%
%increase = 25%
Therefore, percent increase in marios hourly pay rate is 25%
To solve this equation you can plug in these numbers into the equations, so for example you can that the equation a-3b=9 and the points are (-9,-6). you would then insert the numbers so you would have the equation (-9)-3(-6)=9. simplify -9+18=9 and there you have it, the answer is (-9,-6)
