Answer:

Below in bold.

Step-by-step explanation:

f(n) = |-2n| - 6

The vertical lines about the -2n mean the 'absolute value' of the expression So if -2n is negative  the absolute value is positive.

n = 19 , f(n) = |-2*19| - 6 = |-38| - 6

= 38 - 6 = 32.

In the same way:

n = 20, f(n)  |-40| - 6 = 40 - 6

= 34.

n = 21, f(n) = 36

n = 22, f(n) = 38.
