The temperature dropped 3 degrees every hour for six hours. The temperature started at 0 degrees. What was the new temperature? hurry

-18 degrees

Step-by-step explanation:

3 x 6 (For the degrees and hour)

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
