99 POINTS.... PLEASEEEEE HELP !!!

Answer 1

You have a lot of questions here, I can help with some.

1) To find the inverse, switch the x and f(x) and solve for f(x).
x = 3f(x) - 7
x + 7 = 3(f(x)
(x + 7) / 3 = f(x)

2) It is a function, because each input pairs with only 1 output.

3) Any diagonal line would be a function.

4 - 8 (We can't do without the diagram)

9) f(-9) = 3(-9) - 6
    f(-9) = -27 - 6 
    f(-9) = -33

10) f(-2) = 42 + 3
      f(-2) = 45
