Okay so I'm guessing that they are two different formulas the f(x)= 3x and the f(x)= -5x-2. If that's is true then you would just have to plug in -2 to the x's. So then it would be f(x)= 3(-2) which if you solve it would give you f(x)= -6 and for the second one it would be f(x)= -5(-2)-2 so then you would solve for it and get f(x)= 8.

Step-by-step explanation:

$A \cap C$ denotes the set of elements in both A and C, which is $\{20, 24, 28\}$ .
$B^{C}$ denotes the complement of set B, which is the set of all elements that are in the universal set that are not in set B. In this case, this set is $\{3, 4, 5, 6, 8, 11, 13, 16, 17, 19, 20, 22, 23, 24, 25, 26, 27, 28\}$
