Let u = <-1,3> V = <2, -4> and w = <1, -2> find:
u dot w = ?

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

3+x

step-by-step explanation:

answer:

c) the x-coordinate of the center of the circle increases by 3
