Answer:
Step-by-step explanation:
Given
Required
Find 
First, we calculate the inverse function
Express f(x) as y
Swap the positions of x and y
Solve for y: Add 4 to both sides
Square both sides
Divide both sides by 2
Express y as an inverse function
Next, solve for:
Substitute 6 for x
Answer:
n = 3
Step-by-step explanation:
It is given that W is between X and Y. It means,
WX = WY
or
XY = WX+WY
We have, WX=6n-10, XY=17, and WY=3n
So,
17= 6n-10+3n
Adding both sides 10
17+10= 6n-10+3n+10
27=9n
n = 3
Hence, the value of n is 3.

Step-by-step explanation:
For the first question, you simply put an EMPTY circle above 2 and draw an arrow from it all the way down to -3. The reason why we put an empty circle is because there is no equal sign below it.
For the second question, you put a FILLED circle above 4 and draw an arrow from it all the way down to -3. The reason why we use a filled circle is because x is less than OR equal to 4.
