Answer: 
Step-by-step explanation:
To find the inverse of a function start by replacing f(x) with x and replace the original x with y.
Now solve for y
Finally, replace y with the inverse of f(x), 
The answer is 4 and 9, this is because 2*2=4 and 3*3=9, so their square roots are 2 and 3
Answer:
The answer to this question is A
84 to 62. You have to subtract 146-84 to get the number of girls from the class.
The answer is (5,3). You need to equal both sides out. So 5x-22=4x-17. That will give you x=5. After that you substitute 5 for x in one or both of the equations and get that y=3. Hope this helps!
