Using the function f(x)=5x4+2x3−3x2−x−8 and Descartes' Rule of Signs, which are possible combinations of positive, negative, and imaginary zeros?

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

the answer is 8.64
