How do I find the domain and range of this

Domain is the x values from the lowest x to the highest x values used.

Range is the y values from the lowest y to the highest y values used.

Domain : (-4,5)

Range: (0,4)

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

move it to the other side
