13 The famous painting of the Mona Lisa is protected by a glass cover that is 1 inches thick. Which value is
25
equivalent to 13?

the range is 19

step-by-step explanation:

the range is biggest number minus the smallest, so in this case it would be

41 - 22 = 19

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2
