13) Which graph represents a non-proportional relationship?

B

Step-by-step explanation:

Proportional relationships go through the origin (0,0) and have a constant rate of change.

Regarding proportional relationships, when graphed the line should be straight and go through the origin (0,0)

All graphs appear to have straight lines.

However graph B has a line that doesn't go through the origin, therefore B represents a non proportional relationship

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 1 becuz if it were 1.0 that would rip apart the entire so ya. : )
