To find an inverse you switch x and y for a function and solve for y. I will do fx.
X=1/2f(x)'-2
X+2=1/2f(x)'
2x+4=f(x)'
I used ' to represent inverse and since f(x)' =g(x) it is verified
Hi!
We know that there are three measures and each has a different amount of notes. To find the total we add them all up.

Answer:
d) 2.75
Step-by-step explanation:
![\left[\begin{array}{cccc}Credit&Letter&Grade&Product\\4&A&4&16\\2&D&1&2\\3&B&3&9\\3&C&2&6\end{array}\right] \\\\](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bcccc%7DCredit%26Letter%26Grade%26Product%5C%5C4%26A%264%2616%5C%5C2%26D%261%262%5C%5C3%26B%263%269%5C%5C3%26C%262%266%5Cend%7Barray%7D%5Cright%5D%20%5C%5C%5C%5C)
If we sum the products we got ![16+2+9+6 = 33](https://tex.z-dn.net/?f=16%2B2%2B9%2B6%20%3D%2033)
And, to find the average we divide in the total number of credits
![\frac{33}{4+2+3+3} = 2.75](https://tex.z-dn.net/?f=%5Cfrac%7B33%7D%7B4%2B2%2B3%2B3%7D%20%20%3D%202.75)
