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

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{1}~,~\stackrel{y_1}{4})\qquad (\stackrel{x_2}{5}~,~\stackrel{y_2}{1})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{(5-1)^2+(1-4)^2}\implies d=\sqrt{4^2+(-3)^2} \\\\\\ d=\sqrt{16+9}\implies d=\sqrt{25}\implies d=5$
