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.

Answer:g(f(x))= x^2 +6x+5
Step-by-step explanation:
g(f(x))= x^2 -4
g(f(x))= (x+3)^2 -4
g(f(x))= (x+3)(x+3) -4
g(f(x))= x^2 +6x+9-4
g(f(x))= x^2 +6x+5
