Thank you for the opportunity to help you with your question!

1) f(2)= 3(2) +2 = 8

2) f-1(3) = f-3

For the second question, you just have to basically multiply -1 times 3, which is -3. Following, the answer is f-3.

3) 2y + 14 = 4y - 2

14+2= 4y-2y

16=2y

y=8


So, the first one and the third one has the same result.

Please let me know if you need any clarification. I'm always happy to answer your questions.
